The Megger SMRT410 and 410D Multi-Phase Relay Test Systems are portable units (16.4-19.2 kg) for testing electro-mechanical, solid-state, and microprocessor-based relays, offering up to 4 voltage (0-300 V/150 VA) and 6 current channels (32 A/200 VA continuous, 60 A/319 VA short-term, up to 240 A/1276 VA parallel with DIGEN).
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 SMRT410D’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 comprehensive utility and industrial relay testing.
