Chapter 1. Getting Started
1.1 Hardware Requirements
1.1.1 F2000 & F6000 Power System Simulators
The TransWin software runs transient waveforms on the F2000, F2250 and F6000 family of
power system simulators. The F2000 simulators require the F2860 Transient Waveform
Generator option to play back transient waveforms. The F2250 simulators require the F2865
Transient Waveform Generator option to play back transient waveforms.
The TransWin software also runs Dynamic tests using the SSIMUL macro on the F6000 family
of power system simulators. The F6000 simulators require the F6910 Simulator Control and
Automation Module option to play back transient waveforms.
The Analog Input Measurement (AIM) section requires F6150 or F6150A Power System
Simulators equipped with the F6820.
1.1.2 Computer
TransWin requires a PC-compatible computer with the following features:
• Intel Pentium or Intel compatible CPU, 300 MHz or faster recommended for acceptable
performance.
• 64MB of RAM minimum.
• 800x600 or higher resolution-VGA display adapter.
• Windows 98SE, Windows 2000, Windows XP, or Windows NT version 4.0 or higher.
• CD-ROM drive used to install the software.
• At least 100MB of free disk space.
• Pointing device such as a touch pad, mouse, or a track ball.
• Serial port for communication to the F2000 and F6000 instruments.
Alternatively, communication to the F6000 CPU1 can use a PC network interface card
using coaxial cable with a BNC-to-BNC Network port of the F-series power system
simulator. The IP address is set by TRANSWIN. Communications to the F6000 CPU2
can use the 10/100 RJ45 with a CAT5 or better crossover cable.
1.2 Software Installation
The TransWin software is delivered on a CD-ROM disk.
1. Insert the disk into the CD-ROM drive on your computer.
2. Open the CD-ROM drive with Windows Explorer, and execute the Setup.exe file in the
D:TranswinDisk1 directory (where D: is the drive letter for the CD-ROM drive). To
execute the setup file, double-click on the icon that appears or the entry on the drop-
down list labeled Setup.exe.
3. Follow the on-screen directions. Note that you may change the installation directory, if
desired.
10. TransWin User Guide
2 72A-1847 Rev B. 11/05
Some sample COMTRADE records are included in the installation, so that it is possible to start
using TransWin right away.
1.2.1 Starting TransWin
On the task bar at the bottom of the Windows screen, click on Start (or press the Windows key
on the keyboard, if there is one), and select Programs | TransWin. If desired, you can create a
shortcut to TransWin and click on the desktop icon.
1.2.2 Startup
At startup, TransWin momentarily displays a picture, called a splash screen, showing simulation
testing (see Figure 1.) A main window appears with a File | Open dialog box. First, open a
COMTRADE .cfg file to perform any actions in TransWin for transient playback. When a
COMTRADE file is open, all channel traces appear, and TransWin becomes operational. For
first time users, select any of the sample .cfg files to open.
Figure 1. TransWin Splash Screen
1.3 COMTRADE Files
TransWin interprets file data that conform to IEEE C37.111-1999, Common Format for
Transient Data Exchange (COMTRADE) for Power Systems. TransWin also supports files in the
older 1991 specification (IEEE C37.111-1991).
For details on the files and file formats that define a COMTRADE record, refer to the IEEE
specification. For convenience, a summary of the COMTRADE specification is included in
Appendix A of this manual, showing the differences between the 1999 and the 1991
specification.
For information on how to create COMTRADE files from DFR recordings or from power system
modeling programs, refer to the specific manufacturer’s documentation.

Chapter 2. Menus and Toolbar
2.1 View Space for Transient Playback
As Figure 2 indicates, the view space initially shows all analog and digital channels contained in
the COMTRADE recording, as shown on a horizontal time axis (the X Grid) in milliseconds.
The channels appear from top down in order of their index number, as defined in the .cfg file.
Using the Data Properties sheet, you can remove channels from the view space for clarity. You
can select channels that remain in view for playback through both the F2000 and the F6000.
Figure 2. Layout of TransWin Screen
Note: On the view space, the overlay part of the Data Properties displays data readout of values
selected by the Cursors. To see the data readout, click the Hide Properties button.
2.2 Cursor Position
There are three cursors, Cursor1, Cursor2, and the Insert Cursor. Initially, only Cursor1 and
Cursor2 appear visible: Cursor1 appears at the left end of the view space and Cursor2 appears at
the right end of the view space. You can select an Insert Cursor to locate the sample at which to
insert a selected part of a waveform. The Insert Cursor appears at the left end of the view space.
Data PropertiesView Space
12. TransWin User Guide

To move a cursor, place the mouse pointer over the cursor, hold down the left mouse button to
select, and drag the cursor to a new position. Release the mouse button to stop cursor movement.
2.2.1 Coarse Positioning
Use the mouse to drag a cursor. The amplitude and sample number appear in data readout areas
you can see when you close the Data Properties window. (Click the Hide Properties button to
close the Data Properties window.)
2.2.2 Fine Positioning
Select the cursor with one mouse click. Use the left- and right-arrow keys to move the cursor one
sample at a time; the Tab key - 10 samples at a time; and the Control key with the left- and right-
arrow keys - 100 samples at a time.
2.2.3 Cursor Color
To make the cursors more visible, select the Display tab on the Data Properties, and adjust the
color and line quality. Dash-dot line quality may improve visibility.
2.2.4 Data Readout
The right hand side of the view space shows the amplitude for each channel at the position of
Cursor1 and Cursor2. The amplitudes appear in the same color as the cursor. In the lower right
corner of the view space, the sample number selected by each cursor appears for Cursor1 and
Cursor2—each number in the same color as its cursor. Hence, it is a good idea to use different
colors for each cursor. If the Insert Cursor is selected, its value is likewise displayed.
The samples are identified in milliseconds (corresponding to the time axis), and as a sample
number.
Note: Data Properties hide the data readout; so click the Hide Properties button to view the data
readout.
2.3 Data Properties
The Data Properties window appears when TransWin opens a COMTRADE record. There are
four tabs that describe data shown in the view space; this data comes from the .cfg file. However,
the property sheet overlays the right hand part of the view space thus hiding the amplitude, units,
and sample number of individual data points selected by the left and right cursors.
2.3.1 Hide Data Properties
To hide the properties, click the Hide Properties button, or right click the mouse to pop up a
context menu, and click on Property to uncheck it. This reveals the right hand part of the view
space.
2.3.2 Restore Data Properties
To restore the data properties, right click the mouse, click Property to check it, and the property
sheet reappears. Or, select Windows on the menu bar and click Properties.

Chapter 3. Transient Playback
3.1 Open a COMTRADE File
Use the File | Open command to select a COMTRADE .cfg file, and open the COMTRADE record. The
View Space displays all the channels. Examine the data properties to understand what the waveforms
represent.
3.2 Examine Data Properties
The data property sheet has four tabs.
3.2.1 General Tab
This is read-only information from the .cfg file that includes the station name, number of analog
and digital channels, date of recording, start time and trigger time. The Line Frequency, Sample
Rate, and Number of Samples are important for testing.
3.2.2 Display Tab
When first using TransWin, it is important to configure background and grid colors, cursor
colors, and cursor line quality (Cursor Type), to make the view space more easily readable. Use
the Display tab to remove or add channels to the view space, depending on what playback you
desire.
3.2.3 Colors
Click a color button to pop up a color dialog box for that item. Select a basic color or a custom
color from the expanded color dialog. Select colors with care, because of foreground/background
interference that can easily make the view space unreadable. First select background and grid
colors; then, select cursor and units colors. Make the cursors distinctively different in color, with
good contrast to the background. Also choose a line quality as Cursor Type.
.
3.2.3.1 Channel Waveform Colors
Set Channel waveform colors individually on the Analog or Digital tab.
3.2.3.2 Color Scheme
You can save Color selections for channels in one of the predefined schemes. Select the scheme
number and click the <SAVE> button to overwrite any previous selection for analog and digital
channel colors. Note, however, that the colors for cursors, background, grid, and units are global
values. They are saved and remain in effect from one execution of TransWin to another.
Note: When printing a waveform, set the background color to white; otherwise, the printout will
be very black.
18. TransWin User Guide
10 72A-1847 Rev B. 11/05
3.2.4 Cursor Type
You can change the line quality of the cursors to improve visibility. A dash or a dash-dot
combination may make the cursors more visible.
3.2.5 XGrid Count
Change the number of x-axis divisions to the right of the origin by entering a number from 1 to
100. Click the Apply button. A value of 1 is minimum, and any value larger than 100 is not
useful.
3.2.6 Select Channels
Summary check boxes select all Analog or Digital channels for the view space. Uncheck these
boxes to remove all channels, and then select individual channels for display in the scroll
window underneath. Click the Apply button for the selections to take effect. Note that individual
channels are labeled analog (A) or digital (D), and the channel name is given. Unchecked
channels do not appear in the view space, but are not deleted from the file. Recheck the box and
click <Apply> to restore these channels to view.
3.2.7 Superimpose Channels
Use these check boxes to superimpose the selected voltage channels into one composite trace;
similarly for current channels. Check or uncheck these boxes and click <Apply>.
3.2.8 Hide Properties
Click this button to hide the property sheet. Use the right click menu to restore it.
3.2.9 Analog Tab
Properties of each analog channel appear one at a time. The channels appear in graph index
order, as defined in the .cfg file. The index number is shown. To step through the channels, one
at a time, click the large arrow keys, forward or backward. The stepping wraps around between
top and bottom.
Note: The selected channel is marked on the right margin by a “<” symbol. As you click the
large arrow keys, the “<” symbol moves to the adjacent channel.
The channel scale factors and maximum/minimum values appear. A color button allows the
waveform color to change. A check box allows you to remove or restore the channel to the view
space.
3.2.10 Digital Tab
Properties of each digital channel appear one at a time. Click the large arrow keys to step through
the digital channels, the same as for the analog channels. The selected digital channel is marked
by a second “<” symbol. You can modify the color of the channel waveform and remove the
channel by unchecking the check box, the same as for analog channels.
19. TransWin User Guide
72A-1847 Rev B. 11/05 11
3.3 Prepare Test Data
3.3.1 Select Channels for Playback
On the Data Properties Display tab, select the channels you will use for test playback. If there
are many channels in the COMTRADE record, and only a few are to be used for the test,
uncheck the “Select All” check boxes, and then check only individual channels. For example, it
may be sufficient to play back only 3 voltage and 3 current channels, leaving out any digital
channels or neutral analog channels, if the relay being tested would not see those signals in
service.
3.3.2 Set Channel Colors
On the Data Properties Analog and Digital tabs, make any changes to the channel color, to
enhance visibility against the background color in the view space. Click the arrow buttons to step
through each channel.
3.3.3 Position the Cursors
Use Cursor1 and Cursor2 to encompass part of the waveforms of all channels. Initially, Cursor1
is at the left border and Cursor2 is at the right border of the view space. Select a cursor with the
left mouse button and drag it to some point on the waveform. Use the left-arrow and right-arrow
keys for fine-tuning the position. (Hide the Data Properties to see the time position readout on
the lower right.)
3.3.4 Remove Data
Select Edit | Remove on the Menu bar to remove the selected section of the waveforms. This
removes all data between Cursor1 and Cursor2 from the view space. Use this to remove
excessive cycles of prefault or postfault data, or to reduce the duration of the recorded fault.
3.3.5 Insert Prefault or Postfault Data
To add a selected section of the waveforms as either prefault or postfault data from the Menu
bar, select Edit | Add Prefault or Edit | Add Postfault. A dialog box asks how many repetitions to
add. Enter a number and click OK. The prefault or postfault waveform is extended with the
inserted waveform. Use this to create additional prefault time to allow the relay to initialize, or
to provide plausible reset or reclose conditions.
3.3.6 Insert Waveform Segment
To insert the selected section of the waveforms at any position in the channel recording, use the
Insert Cursor. On the menu bar, select Edit | Insert Signal | Position Insert Cursor. The Insert
Cursor appears on the left hand edge of the view space. Select it with the left mouse button and

or F6000, serial port, or Ethernet parameters.
3.4.2 F6 Sources Configuration
Use the Preset–Configuration dropdown list to select the desired Doble source configuration;
e.g., 3 voltages and 3 currents, 3 voltages and 3 transient currents, or 3 voltages and one 450VA
high current source. Sources and ranges are then displayed in a source table. Select a name for
each source; e.g., I1, I2, and I3 for currents, VR, VS, and VT for voltages. Analog channels will
be assigned to these Doble sources for playback.
3.4.3 Assign Channels and Test Parameters
On the Menu bar, select Configuration | Sources and Timers. Note that the assignment of
channels to sources is one-to-one; that is, you can assign a channel to only one source. However,
you do not have to assign all channels, and you do not have to use all Doble sources in a
playback.
3.4.4 Analog Tab
A table of sources and channel assignments appears (see Figure 3). To assign a channel to a
Doble source, click on Channel Name in a source row. A selection button appears. On clicking
this button, a list of suitable sources appears; e.g., for a voltage source, a list of voltage channels
appears. Select a channel name to map to the Doble source.
TransWin recognizes a voltage or a current channel by the unit of that channel. The recognized
unit names are: V, KV, A, and KA.
To delete a channel assignment, select the row and click the Clear button. Click <OK> to apply

3.4.6 Timers Tab
To set up a test, arm a timer on the Timers tab. During the playback, if you intend to time more
than one event, select one timer for each event.
3.4.6.1 Arm a Timer
There is one timer associated with each Doble source. To arm a timer, click a Timer Name cell
and type a descriptive timer name such as Overcurrent Pickup. Timer units default to
milliseconds, but you can select Cycles and Seconds from the dropdown list.
3.4.6.2 Sense Condition
When a timer row is selected, click the Sense Condition select button to see a list of sense
conditions: O→C, C→O, ON→OFF, and OFF→ON. Select one for the test.
3.4.6.3 Starting Sample
Enter the sample number at which the timer will start during playback. To find a sample number,
hide the data properties sheet, so channel values and sample numbers are visible. Select Cursor1
or Cursor2 and move it to a timer start position on the waveform; for example, at fault inception.
The time in milliseconds and the sample number for cursor position appear in the lower right of
the view space, in the same color as the cursor. (The difference in time and samples between
Cursor1 and Cursor2 also appears in parentheses.)
3.4.6.4 Test Result Criteria
You can enter an expected time result for comparison to the actual time recorded by the test. For
Pass/Fail results, enter a ± tolerance, in percent. These fields are optional.
3.4.6.5 Timer Name
This is a descriptive name for the event being timed; for example, Overcurrent Pickup.
3.4.7 States Tab
The States tab allows the user to divide any transient file into three states: PreFault, Fault, and
PostFault. The cursor position defines the three states. The PreFault state is defined as the
samples from the start of the file to the position of the left cursor. The Fault state is defined as
the samples between the position of the left and right cursors. The PostFault state is defined as
the samples from the position of the left cursor to the end of the file.
Two ways exist to transition from one state to the next: Count and Sense. The user can select
from the “Loop Until” column. TransWin will loop, or repeat the state in two ways: First, if the
“Sense” checkbox is checked (the number of times entered in the “Count” field) or, second, if the
“Sense” condition is met, whichever occurs first. If the checkbox is not checked, the state will
advance when the state is repeated the number of times shown in “Count.”
If the “Sense” checkbox is checked, the user must define which input to use by selecting the
corresponding source name in the “Source” dropdown box. Next, the user must select the sense
condition that will cause the transition event in the “Conditions” dropdown box. Last, the user
must select when the state transition will occur relative to the sense condition. The selections are
“Immediate” and “At End of Sample.” Selecting “Immediate” will cause the transition as soon
23. TransWin User Guide
72A-1847 Rev B. 11/05 15
as possible regardless at which sample the sense input occurs. Selecting “At End of Sample”
will cause transition to occur at the end of the state regardless at which sample the input event
occurs.
3.4.8 Comments Tab
You can enter free format text. The time stamp of the last test also appears above the test area.
Note: Configured test data, including channel assignments, timers, and comments are associated
with the COMTRADE file being viewed. Opening a new COMTRADE file allows new
assignments to be made, without losing those made for another file. Now the test is ready to run.
3.5 Run the Test
Ensure all source connections to the proper relay terminals, and any relay trip output is
connected to the logic input identified in the F6000 Configuration Timers tab. Select TEST on
the menu bar and one of the following options.
3.5.1 Battery On/Off
If battery simulator voltage is needed to power the relay, select Test | Battery ON/OFF from the
menu bar. Select ON or OFF and the correct amplitude.
3.5.2 Run
This option allows you to play the configured digital and analog Comtrade channels through the
F6150 Series instrument.
3.5.3 Run Continuously
Download the waveform for each assigned channel to the Doble instrument. This may take some
time, so progress is updated on the Run dialog. Sources are turned on and playback is started.
Status is monitored, and when playback is complete, the Run dialog is replaced by the F6000
Configuration Timers tab, which shows the test time result. The time stamp is recorded on the
Comments tab. To stop a test, press <Enter> or click <Stop> on the Run dialog box.
3.5.4 Run Go-At
Use this option to run a satellite synchronized, end-to-end test. First, on the menu bar, select
Configuration | Communication, and set Synchronize to Satellite. If you have not done this, an
error message occurs when the Run Go-At option is selected. Otherwise, proceed to set the
satellite time at which to start the test. The waveform for each assigned channel is downloaded,
and playback begins when the satellite time setting is reached.
3.5.5 Run Preset…Until
This option is similar to Run State Transition, but starts the prefault state immediately and Go At
starts at the fault state.
3.5.6 Run State Transition
Plays the states defined on the States tab of the Sources and Timers starting with the prefault
state at Go-At time.

Chapter 4. Analog Input Measurement (AIM)
The AIM Configuration interface works together with the F6820 Analog Input Measurement.
The F6820 option equips the F6150 with the AIM board which allows the Logic Inputs to make
analog record as well as the digital ON/OFF. The recording function is setup using the AIM
Configuration located within the TransWin software versions 2.03 and higher.
Use the AIM recording functions to set the eight logic inputs on the front of the F6150 to record
in an analog or digital manner. Several different methods can start or trigger the recording
ranging from a contact status change to a voltage level shift. Once the recording is complete, it
is retrieved and saved in a COMTRADE compatible file viewable by the TransWin transient
viewer or any other COMTRADE viewer.
4.1 Recording only

This is how to set up the Trigger, or start event, which will start the record process. The choices
are Immediate, Preset State, Digital Input, Source and Analog Input. Other then the Pre-Trigger
length entry field, the other fields change with the Source selection.
4.2.2.1 Source: Immediate
With this selection, the recording starts as soon as you download the recording parameters. This
mode is independent of SSIMUL and Transient Playback.
4.2.2.2 Source: Preset State
With this selection, the trigger start event starts a state. Run this mode with SSIMUL or
Transient States Playback.
State Number
Use this option to enter the state number that will trigger, or start the recording process.
4.2.2.3 Source: Digital Input
With this selection, the trigger start event is the logic transition of the selected input. This mode
is independent of SSIMUL and Transient Playback.
Digital #
Allows you to select which of the eight F6150 inputs is defined or selected as the trigger.
Transition
Use this option to select the transition-at-will trigger or to start the recording. The
selected input is set to “Contact” and the selections are Open-to-Close (O→C) and Close-
to-Open (C→O). The selected input is set to “Potential” the selections are Potential Off-
to-Potential On (OFF→ON) and Potential On-to-Potential Off (ON→OFF).
4.2.2.4 Source: Source
With this selection, the trigger start event is a percentage of the amplitude of the range of the
selected source. This mode is independent of SSIMUL and Transient Playback.
Amplitude
Use this option to enter the percentage of range that will trigger, or start the recording
process. If you enter 25% and the range of the selected source is 75V, the recording will
start when the voltage across the input reaches a value of 18.75 Volts.
28. TransWin User Guide

With this selection, the trigger start event is a percentage of the amplitude of the range of the
selected/defined input. This mode is independent of SSIMUL and Transient Playback.
Amplitude
Use to enter the percentage of range that will trigger or start the recording process. If you
enter 25% and the range of the selected input is 250V the recording will start when the
voltage across the input reaches a value of 62.5 Volts.
Channel
Allows you to select which of the eight F6150 inputs is defined as the trigger.
4.2.2.6 Source Enable
This option allows you to select the configured F6150 source you wish to enable for recording.
The Source Enabled list is empty until you configure the F6150. If the Source Enabled list is
empty, you must close the AIM interface window (see Figure 7).
Configure the F6000 instrument and reopen the AIM interface. You do not have to connect the
source output to one of the inputs to record the source. Using the error signals, the sources are
record internally in the source’s feedback circuits.
Place a check mark in the source’s “En” checkbox to enable a source for recording. Recording
does not occur for sources without check marks.

4.2.3 Channel Information (Info) Frame
This section describes how to configure the Logic Outputs, Logic Inputs, and select which
input(s) to record (see Figure 8).
.
4.2.3.1 Number
You have several ways to select and modify the Logic Output and Logic Input. One way is to
directly type the number (1-8) of the Logic Input or the Logic Output into the Number field. The
other way is to use the increase (right) arrow or decrease (left) arrow to move the number to the
correct Logic Input or Output. In either case, the number in the Number field refers to both the
Logic Input and the Logic Output.
Figure 8. Logic Selection
4.2.3.2 Logic Output
You can set the default status of the Logic Output selected by the Number field. The two
choices are Normally Open (N.O.) and Normally Closed (N.C.). This selection is not very useful
at this time as any use of the selected Logic Output in SSIMUL and the Transient Playback
overwrites the selection (see Figure 9).
The other way to set the default status of the selected Logic Output is by clicking on the desired
Logic Output’s contact icon. Clicking on an Open Contact icon changes the Logic Output’s
default state from Normally Open to Normally Closed. Clicking on a Closed Contact icon
changes the Logic Output’s default state from Normally Closed to Normally Open.
The contact icons also indicate the Logic Output’s defined Default state.
Box show the currently selected
Input.

4.2.3.3 Logic Input
You can configure the Logic Input selected by the Number field and enable the input for
recording. The fields within the Logic Input Group change with the Logic Input Type selection.
You can define the Logic Input as either an Analog Input or a Digital Input. The Type selection
defines the type of Logic Input (see Figure 10).
Figure 10. Logic Input
Type: Analog
The Analog selection defines the Logic Input selected by the Number field as an analog input.
Range:
This option sets the range of the selected input. This choice is only available for Analog Input.
There are four ranges for the analog input: 250 V, 25 V, 2.5 V, and 250 mV. To get the
resolution, select the lowest range that will record connected values.
Primary (Pri) Value/Unit:
These selections set the value and units of the primary side of the scale factor. The choices for
primary units are KA for kilo-amps, A for amps, KV for kilovolts, and V for volts.
Secondary (Sec) Value/Unit:
These selections set the value and units of the secondary side of the scale factor. The choices for
secondary units are V for volts and mV for millivolts.
Display:
The Display setting allows you to select whether to record the analog value with primary scaling
or secondary scaling. You have a choice of SEC for secondary scaling and PRI for primary
scaling.
Logic Input 1 is defined
as an Analog input.
Logic Input 2 is defined
as a Digital input.
NCNO
31. TransWin User Guide
72A-1847 Rev B. 11/05 23
Entering Ratios and Scale Factors:
Sometimes it is necessary to record a value that is higher than the highest range of 250V RMS.
Or in some cases, the values could be too low to see accurately on even the lowest range. The
analog inputs will only record voltage. To record amps, perform the following:
1. Use the Primary Value/Units, Secondary Value/Units to set the scale factor.
2. Ensure the range of the Analog input is set correctly to record the secondary value.
3. Use the Display selection to select whether to record in primary or secondary values.
Examples:
Using a voltage step down transformer, you need to record 480 VAC using a 480:120, or 4:1
transformer.
1. Set Primary Value to either 480, or 4.
2. Select the V (volts) for the primary units.
3. Setup the secondary value of the scale factor by entering either 120 (if you entered 480 in
the Primary value) or 1 (if you entered 4 in the Primary value).
4. Select V for volts as the secondary units. Since the secondary or recorded value is going
to be around 120 VAC, set the input range to 250V.
5. Select PRI (primary) for the Display setting to view the recorded values in terms of the
480 volt bus or SEC (secondary) to view the recorded values in terms of the 120 volt
secondary.
With a clamp on the current probe, you wish to use a 10mV/A clamp on the current probe.
1. Enter 1 for Primary Value.
2. Select the A (amp) for the primary units.
3. Setup the secondary value of the scale factor by entering 10 in the field.
4. Select mV for millivolts as the secondary units.
5. Select the correct range to record the maximum current. If the maximum current is fewer
than 25 amps, use the 250 mV range. If the maximum current is going to be over 25
amps, select the 2.5 volt range.
6. Select PRI (primary) for the Display setting to view the recorded values in amps.
Type: Digital
The Digital selection defines the Logic Input selected by the Number field as a digital input.
Record digital inputs as either a one or a zero. You must define what represents a one and what
represents a zero.
Logic Type:
This selection sets the mode of the selected digital input. The two modes are Potential or
Contact.
32. TransWin User Guide
24 72A-1847 Rev B. 11/05
Potential:
The Potential selection places the digital input into potential mode. In potential mode, the device
of the connected input supplies the voltage; that is, the input looks for voltage. The two states
are Voltage On (ON) and Voltage Off (OFF). The Threshold selection determines what level is
on and what level is off.
Contacts:
The Contacts selection places the digital input into contact mode. In contact mode, the
connected input supplies a dry contact to the device where the input is supplying voltage.
Contacts Closed and Contacts Open represent the two states.
Threshold:
This selection sets the voltage level for the input considered ON. The Threshold section is only
active when the Logic Input Type is at Potential.
1.5V:
With 1.5V selected, the ON state is reached when the voltage across the digital input is at or
above 1.5 VDC. The digital input is in an OFF state when the voltage across the input is less
than 1.5 VDC. Use the 1.5V selection ONLY when the digital input connects to a device that
cannot supply 15 VDC or more.
15V:
With 15V selected, the ON state is reached when the voltage across the digital input is at or
above 15 VDC. The digital input is in an OFF state when the voltage across the input is less than
15 VDC.
Normal State:
This selection sets the normal state of status channel in the COMTRADE configuration file. The
selections change according to the Logic Type selection.
Logic Type Selection: Potential
OFF (0) or ON (1).
Logic Type Selection: Contact
Select either Open (0) or Close (1).
Recording
You have several ways to enable the Logic Input for recording: (see Figure 11.)
1. Place a check in the Recording checkbox of the selected Logic Input.
2. Place a check in the checkbox below the White Connector of the desired input in the

Chapter 5. SSIMUL - STATE SIMULATION
The SSIMUL macro uses stepped sine wave quantities to simulate an evolving fault, represented
by up to 25 states. You can use up to 12 sources, and you can record independent timer sense
events, one per F2000 instrument and one per source on the F6000. This macro investigates
suspected relay misoperations or evaluates protection schemes. It also uses F2250 and F6000
logic output to test reclosers and breaker fail relays.
5.1 Open SSIMUL
1. Start TransWin.
2. Select SSIMUL | Open to load an existing SSIMUL test (see Figure 12).
Figure 12. SSIMUL Option Screen
5.2 Configure the SSIMUL Tab
To configure the SSIMUL tab:
1. Select Configuration | SSIMUL.
2. Click <New> to create a new SSIMUL test with a new filename (see Figure 13). The
SSIMUL Test View Screen appears.
The Test View screen shows three states. Use the optional ProTesT Power System model to
calculate fault quantities for different fault scenarios. Normally, three states represent
Prefault, Fault, and Post Fault conditions. As you add more states, the View Screen scrolls to
the right, one state at a time.
Create a state by defining the Source name(s) and Frequency. You can define up to twelve
sources, depending on the F6000 configuration setup. Click <Append> to add additional states.
Note: You can specify two frequencies, but there is a limit of two different source
frequencies. Set the frequency of one source (Source 1 of the master F2000 or first source of
the F6000) to a base frequency different from the frequency reference for all other sources.
For example, setting the frequency of Source 1 to FX or FL, and all the other sources to
numerical values: 60.00, 60.00, 120.00…..FX designates the crystal base frequency and FL
designates the line frequency. The frequency for any source must be a harmonic of the base
frequency. (The F6000 does not support FL.)

Enter the amplitude(s) and phase(s) for each defined state. It is possible to approximate point-on-
wave inception of a fault. Rather than setting Prefault source phases to 0°, -120°, 120°, offset all
phases by an arbitrary amount; for example, 90°, -30°, 210°. The fault state occurs on a
reference zero crossing, at which all sources are offset by 90°. The fault, therefore, occurs at a
different point on the waveform.

5.6 End-to-End Testing
For end-to-end satellite synchronized testing, specify the frequency of all sources as FS or FS*2
(up to FS*20) for harmonics. The Max Duration pull-down box contains options for the first
state to start a satellite synchronized test. The software defaults to the Duration option. Duration
represents the fixed number of cycles before stepping to the second state.
Select Go At or Preset Until instead of Duration for state 1.
Note: When using the “Go At” option when a test is run, a satellite time window appears
with a default “Go At” time, the UTC time at which the test will start. The sources turn
on at “0” amplitude, but source values for the first state do not appear until the “Go At”
time.
For the “Preset Until” option, run the test to set up the instrument. The sources turn on
right away at the values of the first state. The transition to the next state does not occur
until the selected UTC time.
Define Go At or Preset Until with a starting time that you have presented and agreed upon with
the test crew at the other end of the line. SSIMUL displays UTC satellite time on the screen and
the time continually updates. Satellite status also indicates the number of detected satellites.

5.7 Configure the Logic Out Tab
1. Click the Logic Out tab and to identify the F225X and F6000 logic output you wish to
use (see Figure 15). You can only select a source from the Source Column.
Note: Each state has separate columns for logic output 1 (L1) and logic output 2 (L2 – not
valid for F6000).
2. To set the logic output, click in the state column in the row for the logic source.
3. Click once for low; twice for high. Clicking a third time changes to reset.
4. Map between:
L1 and L8 for the F6000 (L1 is the default)
L1 and L2 for the F225X (L1 is the default)

5.8 Configure the Results Tab
Click the Results tab to arm timers to start in a specified state and to stop on a sense event (See
Figure 16). (The SSMIL macro initially displays the results for the current test conditions.)
Figure 16. Results Tab Screen
To configuring the Results tab:
1. Click the pull-down list under Timer/Name and select a source name to identify a timer.
2. Select the source name in the Timer Name column corresponding to the timed logic
input.
3. Select the timer start state. The timer starts at the beginning of that state. The pull-down
list shows only those states already defined for the macro. Use this field to start timers for
edge transitions (O→C, C→O, O→C→O, C→O→C, On→Off, Off→On,
Off→On→On, On→Off→On).
4. Select the stop event for the timer; for example, ON Æ OFF for voltage, O Æ C for
contacts. The timer stops when the event occurs, possibly several states later. If no event
occurs before the macro completes, no timer value appears, and Result is No Op.
5. Enter the expected duration in the indicated units, of the timed event in “Expected.” This
field can be left at 0.000, and the actual duration of the event is still reported.
6. Select the timer units: milliseconds, seconds, or cycles.

7. Set the + or - tolerance units in milliseconds, seconds, or cycles.
8. Click Run at the right of the screen to run the test. The Actual Value, Result and Error
fields are populated.

Appendix A COMTRADE Files
A COMTRADE transient record is composed of four different files, two of which are optional.
The required files are a Configuration file (.cfg) and a Data file (.dat). The optional files are a
Header file (.hdr) and an Information file (.inf). The Header file is ASCII text, containing free
format information that you can read or print. The Information file was added in the 1999
COMTRADE specification, and it contains ASCII text in the format of a Windows .ini file; i.e.,
it is divided into bracket delimited sections that contain information more easily read and
interpreted by user application software.
All file names follow the DOS 8.3 format: an 8-character file name with 3-character file extension.
Configuration File (.cfg)
This is an ASCII text file with a specific line-by-line format, where each line is delimited by
carriage return, line feed (CR/LF). Each line contains comma delimited text fields, arranged in a
specific order, so an application program like TransWin can read the data. Data from the .cfg file
are read by TransWin and displayed in the Data Properties window.
Fields added in the 1999 specification are marked with an asterisk (*). An example in quotes follows each
line with comments.
File Format
First Line: Station name, Recording device ID, *COMTRADE Standard revision year
Example: “First Street Substation, 1, 1999” If year is missing, it is assumed to be 1991.
Second
Line: Number of channels total, Number of analog channels, Number of digital
channels
Example: “ 7, 6A, 1 D” E.g., seven channels, 6 analog, 1 digital.
Note: The 1991 specification required that the channel information lines follow in the order
indicated in the second line; i.e., analog channels first, followed by digital channels. In the
example, therefore, 6 lines of analog channel information would follow the number of channels
line, followed in turn by 1 line of digital channel information.

Analog Channel Information
A line containing the following comma delimited fields identifies each analog channel:
channel index number (1, 2, …),
name (e.g., I1),
phase (e.g., A) ,
circuit ID,
units (e.g., kV, V, kA, A),
multiplier (slope),
offset (where slope and offset are linear conversion factors for data points, in floating point notation),
skew time (optional floating point time delay for multiplexed channel scan),
minimum data value of samples in the channel (integer),
maximum data value of samples in the channel (integer),
*primary (channel pt or ct ratio primary factor – 1999 Specification),
*secondary (channel pt or ct ratio secondary factor),
* “P” or “S” to identify whether channel values are primary or secondary quantities.
1991 Example:
“1, VA, A, Line 1, V, 4.531698E-03, 2.265892E-03, 0,-32768, 32767”
1999 Example:
“1, VA, A, Line 1, V, 4.531698E-03, 2.265892E-03, 0,-32768, 32767, 1.2000E+03, 5.0000E+02, S”
Digital Channel Information
channel index number,
name (e.g., Logic 7),
*phase (e.g., A),
*circuit ID,
normal state of channel (i.e., 0 or 1).
1991 Example:
“7, Logic 7, , , 0” — Phase and Circuit ID fields are missing.
Note: Digital channel index must start with next sequential number after the last Analog
channel; one index numbering is used for both.
1999 Example:
“1, Logic 7, , , 0” — Phase and Circuit ID fields are not critical. Digital channel index can start with 1.
Line frequency
“50” or “60” Hertz.
Sampling Rate Information
Number of sample rates (up to 999)
Sample rate in Hertz, Last sample number at sample rate (multiple text lines for multiple rates).
Example:
“1
10000, 3333”

Date/Time Stamps
Date/time stamps for the first data point
Date/time stamp for the trigger point of the recording.
1991
Example:
“02/08/01,09:57:10.000000 Date format is mm/dd/yy, US style.
02/08/01,09:57:10.020000”
1999
Example: “28/02/2001, 09:51:10.000000 Date format is dd/mm/yyyy, European style.
28/02/2001, 09:51:10.020000”
Data file type
(ASCII or BINARY) – determines how to read .DAT file.
Data File (.dat)
The file is arranged as rows (records) and columns (fields) of data, the same order whether in ASCII or
BINARY format.
Each row contains:
Sample number
timestamp (in microseconds)
one data value for each channel.
Note: If the file is BINARY, two-byte words (16 bit) in a record are stored in “little endian” format, least
significant byte followed by most significant byte.
