SMRT36
Megger Relay Test System
DESCRIpTION
For size, weight, and features the SMRT36 is conceivably the
smallest, lightest, highest output powered, complete three phase
relay test system in the world today. The test system may be
customized by adding the number of Voltage-Current, “VIGEN”,
modules needed for specific test applications. The SMRT36 has the
“smart” combination of high compliance voltage and high current
to test all electromechanical, solid-state and microprocessor-based
overcurrent relays, including voltage controlled, voltage restraint
and directional overcurrent.
The SMRT36 with three VIGEN Modules provides a complete three-
phase test system for commissioning of three phase protection
systems. With the voltage channels converted to currents, the same
unit can provide 6-phase current. The SMRT36 VIGEN modules also
provide high power in BOTH the voltage and current channels to
test virtually all types of protective relays.
The SMRT36 test system has the ability to be manually controlled
with Megger’s new Smart Touch View Interface™ (STVI). The STVI,
with its large, full color, high resolution, TFT LCD touch screen
allows the user to perform manual, steady-state and dynamic
testing quickly and easily using the manual test screen, as well as
using built-in preset test routines for most popular relays.
The STVI eliminates the need for a computer when testing virtually
all types of relays. Menu screens and touch screen function buttons
are provided to quickly and easily select the desired test function.
Tests results can be saved to the STVI for download to a memory
stick to transfer or print test reports.
For full automatic testing the SMRT36 may be controlled by Megger
Advanced Visual Test Software (AVTS). AVTS is a Microsoft
®
Windows ® XP ® /Vista™/7 compatible software program designed to
manage all aspects of protective relay testing using the new Megger
SMRT.
ApplICATIONS
Each current channel is rated for 30 Amps @ 200 VA continuous,
up to 60 Amps @ 300 VA for short durations. It has a unique flat
power curve from 4 to 30 Amps that insures maximum compliance
voltage to load at all times. Three currents in parallel provide up
to 180 Amps @ 900 VA for instantaneous tests. With a maximum
compliance voltage of 50 Volts per phase, with just two channels
in series provides 100 Volts of compliance voltage to test high
impedance relays.
