MEGGER SMRT33 RELAY TESTER

For size and low weight, the SMRT33 is conceivably the smallest, lightest, highest output powered; complete three phase relay test system in the world today. The SMRT33 provides high power in both the voltage and current channels to test virtually all types of protective relays used in heavy industrial, distributed generation and low- to medium-voltage distribution substations. The SMRT33 has the smart combination of high compliance voltage and high current to test all electromechanical, solid-state and microprocessor-based overcurrent relays, including high impedance directional ground overcurrent. In addition, the unit includes capability to test IEC 61850 devices
