Product Overview

RENT Megger SMRT46 Multi-Phase Relay Tester (Call for Availability)

    The Megger SMRT46 is a multipurpose, light-weight, field portable test set capable of testing a wide variety of electro-mechanical, solidstate and microprocessor-based protective relays, motor overload relays and similar protective devices. The SMRT46 provides up 30 Amps at 200 VA per phase continuous, or up to 60 Amperes at 300 VA with a 1.5 second duty cycle. Three current amplifiers can be paralleled to provide a maximum of 180 Amperes at 900 VA for testing all instantaneous overcurrent relays. Up to 10 programmable inputs, and 6 programmable outputs provide timing and logic operations in real-time with the output voltage and currents.

    The Megger SMRT46 test system has the ability to be manually controlled with Megger’s Smart Touch View Interface™ (STVI) handheld controller running the new RTMS, Relay Testing Management Software. For full automatic testing the SMRT46 may be controlled by Megger Advanced Visual Test Software (AVTS). 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. Each voltage channel can provide variable outputs of 0- 30/150/ 300 Volts at 150 VA of output power. Automatic range changing is done on-the-fly and under load. For testing a panel of relays or older electromechanical impedance relays, it has a unique flat power curve from 30 to 150 Volts insuring maximum output power to the load at all times.  A 3 channel SMRT46 may be interconnected with 4 more SMRT46 units, providing up to a maximum of 30 current channels.
