Product Overview

RENT MEGGER SMRT46D Multi-Phase Relay Tester (Call for Availability)

The Megger SMRT46D is a multipurpose, light-weight, field portable test set capable of testing a wide variety of electro-mechanical, solid-state and microprocessor-based protective relays, motor overload relays and similar protective devices. The unit can be operated either manually via the built-in touchscreen user interface, or placed under full computer control via the AVTS, Advanced Visual Testing Software, or the RTMS, Relay Test Management Software, running on a PC.  It incorporates a large, easy to read Full Color high resolution, high definition, TFT LCD touch-screen display, which displays metered values such as AC and DC Amperes, AC and DC Volts, and Time in both seconds and cycles.

The test system may be customized by adding the number of Voltage-Current, “VIGEN”, modules needed for specific test applications, with a maximum of 3 channels. For example, the SMRT46D with three VIGEN Modules provides complete threephase testing of three-phase impedance, directional power, negative sequence overcurrent and other devices that require a three-phase four-wire wye connected sources. With a maximum compliance voltage of 50 Volts per phase, two channels in series provide 100 Volts to test high impedance relays. Three currents in parallel provide test currents up to 12 Amperes at 600 VA for testing ground overcurrent relays at high multiples of tap rating.  The SMRT46D can perform acceptance or troubleshooting tests by replaying digitally recorded faults, or EMTP/ATP simulations, in the IEEE- C37.111, COMTRADE Standard format.
