Megger SMRT1 Single Phase Relay Tester front facing

Description

The Megger SMRT1 single-phase relay test system is a standalone unit 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.

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. Test results can be saved to the STVI for download to a USB drive to transfer or print test reports.

For full automatic testing, the SMRT1 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 using the Megger SMRT1.

Supplied with Relay Testing and Management Software (RTMS) for installation on a PC. The software does not require a security dongle or license to operate and can be loaded on as many customer-owned computers as required. The powerful RTMS software can be run directly from a PC providing both manual and automatic test capabilities.

Input rating:	Up to 300 V AC/DC

Binary Output Relays

SMRT1 has an independent, galvanically isolated, output relay contact to accurately simulate relay or power system inputs to completely test relays removed from the power system.
