Kd 10 relay manual

This report is to clarify the basic difference between the obsolete KD-4 / KD electromechanical relay and the present design KD / KD Compensator Distance Relays. KS-3 Out-of-Step Blocking Relay Instruction Leaflet, IL A. IL H. 0 reviews. Type KD and KD Compensator Distance Relay. Year File Size Mb. The KD relay has two major components: com-pensators and tripping units. In the internal schemat-ic of Figure 4 (page37) the compensators are desig-nated T, TAB and TBC, the tripping units, Z (3φ) and Z(φφ). The phase-to-phase unit, Z (φφ) operates for all combinations of phase to phase faults (phase A-B, B-C, and C-A).

KST out-of-step tripping relay ohms The KST relay is used with another distance relay such as a KD-3 relay or the three-phase unit of a KD-4, KD, or a KD to sense an out-of-step condition on a power system and to initiate tripping. Omit this procedure for KD relays. a) for OHM reach KD-4 relays • when the relay is preheated as per I.L., decrease R3A setting by 10% of total R3F and R3A resistance. or • for a cold relay repeat step 1 and adjust R3A so that the contact just opens. No fur-ther adjustment is required. b) for OHM reach KD-4 relays with sub. After the circuit breaker is installed, check all mounting hardware and terminal connecting hardware for correct torque loading.

This test procedure covers the testing and maintenance of the Westinghouse KD medium reach − ohm range) relay. The Westinghouse Protective Relay Division was purchased by ABB, and new relays carry the ABB label. The phase to phase potential rating of this relay is Vac and the continuous current rating is 10 amps with a one second rating of amps.
