MGR-SMRT1 Is a 2 channel, Single Phase Relay Tester.
The SMRT1 has the "smart" combination of high compliance voltage and high
current to test electromechanical, solid-state and microprocessor based overcurrent
relays, including voltage controlled, voltage restraint and directional overcurrent;
test under/over voltage, single-phase impedance, single-phase power, directional,
synchronizing, auto-synchronizing, negative sequence under/over voltage, current
balance, frequency, volts/hertz, reclosing, thermal, and various other relays.
The current channel is rated for 30 Amps @ 200 VA continuous, up to 60 Amps @
300 VA for short durations. It has a flat power curve from 4 to 30 Amps that
insures maximum compliance voltage to load at all times. With a high
compliance voltage of 50 Volts the SMRT1 has the capability to test high
impedance overcurrent relays.
The voltage channel can provide a variable output of 0- 30/150/ 300 Volts at
150 VA of output power, and has a flat power curve from 30 to 150 Volts
insuring maximum output power to the load at all times. With the voltage
channel converted to current, it can perform minimum operating point, slope,
and timing on current differential relays, including harmonic restraint
transformer differential relays (which can be tested one phase at a time).
Includes STVI-1 (Smart Touch View Interface) with common grounded returns, no
Bluetooth, no IEC61850, in standard enclosure with test leads.
Operates with or without computer.
(60 Amps/300 VA rms) per phase.
