What relay types can VA-TEK relay test sets test?
Our relay test sets support all common protection relay types, including overcurrent (ANSI 50/51), differential (87), distance (21), voltage/frequency (27/59/81), directional overcurrent (67), motor protection (49/46/48), transformer differential (87T), restricted earth fault (REF), breaker failure (50BF), synchronizing (25), and reclosing (79) relays. Testing is done through the relay’s conventional current and voltage inputs; IEC 61850 […]
