Are Gutters Necessary? Explore the details now!AmeliaLauren3
Gutters are typically installed at a slight downward slope to allow water to flow freely towards downspouts or drains – the downspout being the vertical pipe attached to the gutters. The water is subsequently transported by the downspout to either the ground or an underground drainage system. Maintaining a gutter system that is free of blockages and functional requires regular maintenance.
But, many wonder in what situations gutters are required and not required. In this ppt we will discuss in detail the matter, ‘Are Gutters Necessary?’

5. Description of Functionality
• 27/59 Under/Over Voltage
Each element has settings for pickup level, drop-off level and Definite Time Lag (DTL)
delay. Operates when voltage exceeds setting for the duration of delay.
• 47 Negative Phase Sequence Voltage
Each element has settings for pickup level and Definite Time Lag (DTL) delays. Operates
when NPS voltage exceeds setting for the duration of delay.
• 59N Neutral Overvoltage
Neutral overvoltage can be used to detect earth faults in high impedance earthed or
isolated systems.
• 74T/CCS Trip & Close Circuit Supervision
The trip or close circuit(s) can be monitored via binary inputs. Detection of trip circuit
failure can be used to raise an HMI alarm (general alarm) and/or output(s).
• 78 Vector Shift
Operates if the voltage vector ‘jumps’ by more than setting during abrupt change in
load.
6. Description of Functionality
• 81 Under/Overfrequency
Each element has settings for pickup level, drop-off level and Definite Time Lag (DTL) delays.
• 81R Rate of Change of Frequency (df/dt)
Each element has settings for pickup level and Definite Time Lag (DTL) delay.
• Programmable Logic
The user can map binary inputs, protection elements, LEDs and binary outputs together in a logical
scheme.
• Virtual Inputs/Outputs
There are 8 virtual inputs/outputs to provide internal logical states to assist in the application of
the functions.
Control Mode
The relay has a control menu with access to commonly
used command operations. Access to the control
commands is restricted by a 4 character control
function password. Each command requires a select
then execute operation, if the execute operation is not
performed within a time window the command is
aborted.
7. Serial Communications
• The relay offers a USB serial port as standard on the front of all units. All of the relays
functions can be set on a PC using Reydisp Evolution via the USB port. The connection is made
with a USB cable and operates with a ‘plug and play’ connection, so no pre-setting of the
relay is required. The front port can be switched off or set to use either the DNP3.0, MODBUS-
RTU, IEC60870-5-103 or ASCII protocols for testing purposes.
• A rear RS485 electrical connection is available on all units for system interface connections. An
internal terminating resistor is provided, which can be connected into the circuit by adding a
wire loop between the relevant terminals.
The rear RS485 can be user selected to be OFF, IEC60870-5- 103, MODBUS RTU or DNP3.0
protocol.
8. Ethernet Communications
• IEC61850 communication is available through an optional EN100 communication module. The
EN100 Module can be ordered with either 2x Electrical RJ45 or 2x Fibre optic LC Ethernet
ports.
• Information on IEC61850 functionality can be found in the following 7SR158 documents:
o Model Implementation Conformance Statement (MICS)
o Protocol Implementation Conformance Statement (PICS)
o Protocol Implementation Extra Information for Testing (PIXIT)

9. User Interface
The operator interface is designed to provide a user friendly method of controlling, viewing
menus, entering settings and retrieving data from the relay. Five buttons are provided for
navigation around the menu structure.
LCD
A 4 line by 20 character liquid crystal display with power
save operation indicates the relay identifier, settings,
instrumentation, fault data and control commands. Up to 6
user programmable general alarms can be configured to
display your own indications on the LCD.
LEDs
A green steadily illuminated LED indicates the ‘Protection
Healthy’ condition. 9 user programmable LEDs are available
eliminating the need for expensive panel mounted pilot lights
and associated wiring.
Relay Information
The device is identified by the rating label on the fascia. The
user can give the device its own unique identity by editing the
‘Relay Identifier’ displayed on the LCD, also space is provided
for a further slip-in label.
10. Data Acquisition-Via Communication Interface
Sequence of event records
Up to 1000 events are stored and time tagged to 1ms resolution
Fault Records
The last 10 fault records are displayed on the relay fascia and are also available through the
communication interface, with time and date of trip, measured quantities and type of fault.
Waveform recorder
The waveform recorder stores analogue data for all poles and the states of protection
functions, binary inputs, LEDs and binary outputs with user settable pre & post trigger data. A
record can be triggered from protection function, binary input or via data communications.
Demand Metering
A rolling record of demand over the last 24h is stored. The demand is averaged over a user
selectable period of time. A rolling record of such demand averages is stored and provides
the demand history.
Real Time Clock
The time and date can be set and are maintained while the relay is de-energised by a back
up storage capacitor. The time can be synchronized from a binary input pulse or the data
communication channel.
11. Construction
• The relay is housed in a 4U high size E4 or E6 case with a removable clear plastic fascia
cover. The plastic fascia cover can be ordered with or without two push buttons to allow the
user to view the settings and instruments without removing the cover.
• Two plastic handles are provided to allow the relay to be withdrawn from its case, contacts in
the case ensure that the normally closed contacts remain short circuited when the relay is
withdrawn.
• The rear terminal blocks comprise M4 female terminals for ring crimp wire connections, to
provide a secure and reliable termination.
12. Reydisp Evolution
• Reydisp Evolution is common to the
entire range of Reyrolle numeric
products. The user can apply settings,
interrogate settings, retrieve events
and fault data.
• Language Editor
The Language editor software gives the user
the ability to customize the text displayed in
