Description

Overview

The Megger SMRT46D is the integrated-display version of the high-capacity SMRT46 relay test system. It offers the same powerful multi-phase output – up to six current sources and three convertible voltage channels – but adds a built-in Smart Touch View Interface touchscreen, so complete tests can be carried out without an external controller or PC.

Each current channel delivers 32 A continuously (60 A short-time), paralleling to 180 A, with series connection available for higher compliance voltage on high-impedance relays. Variable-frequency output, COMTRADE transient playback, a high-precision timer and options for IEC 61850 GOOSE and GPS end-to-end testing make the SMRT46D a self-contained solution for testing the most demanding transmission and generation protection schemes.
