The SMRT410 test system may be customized by adding the number of Voltage-Current, “VIGEN”, modules needed for specific test applications. The SMRT410 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 high impedance directional ground overcurrent.

The SMRT410 provides a complete multi-phase test system for commissioning of protection systems. With up to 4 voltage channels a 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.

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 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 SMRT410 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.


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, just two channels in series provide 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. Using the Ethernet ports, the SMRT410 is literally a “plug and play” unit, where voltage and current outputs can be seamlessly synchronized with other SMRT units outputs for testing more complex test applications such as back-to-back tests.
