Megger SMRT range of relay test sets enables the testing of modern digital self-powered relays as well as the popular new relays with redundant power supplies.The high power
The range, of which the latest addition is the SMRT410 model, has set new standards in the industry for high power, low weight and STVI Touchscreen control.
The SMRT410 test system has the 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 high impedance directional ground overcurrent.
Meets every testing need
The model provides a complete multi-phase test system for commissioning of protection systems. With up to 4 voltage channels and 6 high currents, the SMRT410 meets every testing need. The SMRT410 VIGEN modules also provide high power in both the voltage and current channels to test virtually all types of protective relays.
Touch screen interface
The SMRT410 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, 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.
Maximum compliance voltage
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.
With only 3 currents in parallel, the unit provides 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, it provides 100 Volts of compliance voltage to test high impedance relays.
Each voltage channel can provide variable outputs of 0- 30/150/ 300 Volts at 150 VA of output power, and has a unique flat power curve from 30 to 150 Volts insuring maximum output power to the load at all times. With the voltage channels converted to current, a five channel unit can provide 10 currents.
