The Megger SMRT46 and 46D Multi-Phase Relay Test Systems are lightweight (12-13.65 kg), portable units for testing electro-mechanical, solid-state, and microprocessor-based relays, offering 4 voltage (0-300 V/150 VA) and 3 current channels (32 A/200 VA continuous, 60 A/319 VA short-term, up to 180 A/957 VA parallel). They support overcurrent, impedance, differential, and synchronizing relays, with IEC 61850 GOOSE/SVA, Rogowski mode (2/10/40 V via MLLA), and COMTRADE playback.

Controlled via STVI or SMRT46D’s TFT LCD, they provide manual/auto testing with RTMS Standard/Enhanced, no PC required. Features include high-accuracy metering, multi-unit synchronization (up to 30 currents), GPS end-to-end testing, and a battery simulator (5-250 V). Housed in rugged enclosures (IP30), they meet safety standards (EN 61010-1). The kit includes the unit, RTMS, test leads, carry case, manual, and one-year warranty, ideal for utility and industrial relay testing.
