MI 2792 PowerQ4 Plus
The MI 2792 PowerQ4 Plus is a power quality analyser specially designed for troubleshooting of power systems and devices. Rugged design, long battery autonomy (up to 15
hours), powerful recorders, events and alarms capture, flex current clamps as standard accessory, remote instrument control via optional GPRS modem, ability to synchronize
instruments via GPS make this instrument unique troubleshooting tool. Advanced PC SW package PowerView2 enables detailed analysis of recorded data and automatic
creation of professional test report. Excellent price / performance ratio, small size, advanced measurement methods and loggers are undoubted highlights of the MI 2792.

GPS:
Typical Applications - Observing on two or more points on network
By using two ore more synchronized PowerQ4 Plus instruments by means of GPS Unit, user
can perform simultaneous measurement on the different network points. GPS unit assures
that instruments are synchronized during EN 5010 survey, for example. Additionally the same
configuration can be used for troubleshooting, for example to estimate disturbance impact on
network or susceptible load.
Instruments placement in that case:
• motor - source of disturbance (aggressor),
• server room - victim of disturbance,
• transformer - path of disturbance spreading into network.
By using PowerQ4 Plus recorders (transient, inrush and waveform) user can observe disturbance spreading over the network and estimate impact under various conditions.

GPRS:
Typical Applications
Modem data transfer enables remote handling of the instrument and its data. When the instrument has to be located on distant or hardly accessible place, the modem is the only practical
solution for fast access to the instrument.
Metrel recommend to prepare test system for verification and training before performing actual
measurements at the remote place.
GPRS standard set include:
• GPRS Modem Telit 863-PY,
• USB / RS232 cable,
• Stub Antenna, 54 mm,
• 12 V power supply adapter.
*Optional 5 m antenna cable can be provided upon request.
Requirements for remote measurements
Measurement (remote) site:
• PowerQ4 Plus Instrument,
• Instrument power supply,
• GPRS Modem,
• SIM card with activated data transfer,
• PS/2-USB interface cable,
• Modem power supply,
• Antenna.
Office (local) site:
• PowerView v2.0,
• Internet connection (http web access),
• Open incoming port on office router.

POWERVIEW:
PowerView software is a powerful platform for downloading, analysing recorded data and creation of power quality test reports. PC Software contains a package of
functionalities needed for profound evaluation of power quality phenomena, data comparison and creation of complex test reports. It works in conjunction with Metrel
new generation power quality analysers. For the instruments equipped with GPRS functionality PowerView enables remote control of the instrument as well.
KEY FEATURES:
• User friendly interface: wide range of
quick buttons, possibility to customize the
environment by dragging, docking and resizing the window tabs.
• Structure: downloaded data is organizedinto Windows Explorer-like tree structure.
• “Drag and drop”: downloaded data can
be easily organized into multiple sites and
sub-site locations.
• Data filtering: data in a structure can be
grouped by quantity or by phase.
• Views: depending on selected record
type, different views are available (Record
Information view, Trend Chart view, Table view, Waveform Scope view, Voltage
Quality view, etc.)
• EN 50160 analysis: automatic voltage
quality analysis in compliance with custom
or predefined EN 50160 Power Quality criteria and quick report printing.
• Chart zoom: chart can be zoomed depending on selected in a table value range.
• Remore control: via GPRS communication remote handling of the instrument
and its data can be executed.
• GPS
synchronization:
simultaneous
13
measurement on the different network
points by using 2 or more synchronized
instruments.
• On-line monitoring: when instrument is
connected with PC, real-time observing
of signals and parameters is possible via
PowerView while instrument is measuring
/ recording in the background.
• Export of test results: test results can be
exported to other programs (MS Excel,
MS Word).
• Reports: automatic generation of test reports from the selected views and data
with attached graphs.
• SW update: PowerView checks for new
versions of the application and downloads
updates from the Internet if necessary.
