Single-phase relay test system

  • Small, rugged, lightweight, and powerful
  • Operate with or without a computer
  • Intuitive manual operation with Smart Touch View Interface (STVI)
  • Built-in display (SMRT1D) 
  • High current, high power (75 Amps/400 VARMS)
  • Network interface provides IEC 61850 test capabilities
  • Fully automated testing using RTMS software

The SMRT1 single-phase relay test system and SMRT1D are standalone units that combines high compliance voltage with high current to test electromechanical, solid-state and microprocessor-based overcurrent relays, including voltage controlled, voltage restraint, and directional overcurrent. It can also test under/overvoltage, negative sequence under/overvoltage, single-phase impedance, single-phase power, directional, synchronising, auto-synchronising, current balance, frequency, volts/hertz, reclosing, thermal, and various other relays (see the Applications sections for more).

The SMRT1 can be manually controlled with Megger’s new Smart Touch View Interface (STVI). The STVI is Megger’s second generation of automatic/semi-automatic manual user interface software. With its large, full colour, high resolution, TFT LCD touch screen, it allows you 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 displays metered values such as AC and DC Amperes, AC and DC Volts, and time in both seconds and cycles. Depending on the type of test selected, other values may be displayed, such as phase angle, frequency, ohms, watts, VA, or power factor/dissipation factor. 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 USB drive to transfer or print test reports. The SMRT1D has the STVI built into the unit.

For full automatic testing, the SMRT1 (or SMRT1D) can also be placed under full computer control via the Relay Test Management Software (RTMS) running on a PC. RTMS is a Microsoft Windows XP/Vista/7/8/10 compatible software program designed to manage all aspects of protective relay testing.
