Manufacturing for CEYG has been discontinued . As an alternative, please refer to D60 or P443. The CEY51A and CEY52A are extended range, three-phase, high-speed, single-zone mho directional-distance relays. These relays include three single-phase units with provision for single phase testing. One target and seal-in unit provides indication of operation for all three distance units and the three-phase contacts are brought out to separate terminal studs. A CEY53A is a single phase, extended range, zone-one mho distance relay specifically for shunt reactor protection and includes the normal target seal-in unit.
