Description
Overview
The Megger SMRT43D is the integrated-display version of the SMRT43 three-phase relay test system. It provides the same versatile multi-phase output – up to three current channels and three voltage channels, plus an auxiliary voltage channel – but adds a built-in Smart Touch View Interface touchscreen so complete relay tests can be run without an external controller or PC.
Each current channel delivers 32 A continuously (45 A short-time), paralleling to 135 A, and the system supports variable-frequency output, COMTRADE transient playback, a high-precision timer, and options for IEC 61850 GOOSE and GPS end-to-end testing. This makes the SMRT43D a self-contained solution for testing electromechanical, solid-state and microprocessor-based protection in industrial and utility substations.
