In addition to the current injection units, we offer systems designed for testing voltage relays, frequency relays, G59
scheme relays, df/dt (ROCOF type), vector surge relays, and AVR types. These can also be used in conjunction with
SCITS sets to allow testing of directional relays, power and reverse power relays and distance protection.
