"The sensitive earth-fault relay SPAJ 111 C is designed to be used as a neutral current measuring feeder earth-fault relay, as generator interturn fault protection, as capacitor bank unbalance protection and rotor earth-fault protection. The sensitive earth-fault relay is suited for both primary and back-up earth-fault protection. The input impedance of the energizing circuit of the earth-fault relay is extremely low which means that the relay can lso be energized from low output core-balance current transformers. Core-balance current transformers can be recommended when extremely sensitive earth-fault protection is required. The earth-fault relay can also be energized from a set of three phase current transformers connected in parallel, a so called residual current connection."
