Single-phase relay testing system SMRT1 / SMRT1B

voltagepowerfrequency

The SMRT1/1B single-phase relay test system are units that combine high compliance voltage with high current to test electromechanical, solid-state and microprocessor-based overcurrent relays, including voltage controlled, voltage restraint, and directional overcurrent.

Furthermore, it has the same IEC 61850 capabilities both for GOOSE and SV as its multi-phase siblings.

The SMRT1 single-phase relay test system and SMRT1B are standalone units that combines high compliance voltage with high current to test electromechanical, solid-state and microprocessor-based overcurrent relays, including voltage controlled, voltage restraint, and directional overcurrent.

It can also test under/overvoltage, negative sequence under/overvoltage, single-phase impedance, single-phase power, directional, synchronising, auto-synchronising, current balance, frequency, volts/hertz, reclosing, thermal, and various other relays.

The SMRT1B can be controlled with the Integrated on-board display. It helps substation commissioning teams and field engineers who want to test protection relays efficiently across multiple locations by eliminating dependency on power outlets and the need for extension cords. It delivers full relay test power - extendable to three-phase by using multiple units - with complete freedom of movement anywhere.
