Relay Test Set
 

Padmagiri Enterprises make relay testing set is designed for site testing of protective relays which simulate in common fault conditions under which protective relay will be called into positive function. Periodic field testing is the best way of ensuring the integrity of the protective relays. We offer our relay testing set with specifying capacity to suit different group of proactive relays. The testing set operates on single phase 230V, A.C. 50Hz. Supply. The set is housed in sheet steel cabinet duly powder coated with detachable lid with all the control knobs, switches, terminals etc.brough out on thick backlit panel duly engraved. The set is suitable for testing. Thermal relays, over current relays, earth fault relays, under voltage relays over voltage relays etc.
