Abstract: 858,638. Protective cut-out arrangements. WESTINGHOUSE ELECTRIC CORPORATION. Sept. 15, 1958 [Sept. 20, 1957 (5)], No. 29455/58. Class 38 (5). A polyphase distance protective system comprises means for deriving voltages corresponding to the transmission line voltages, at least one " compensator " having an impedance angle and an impedance corresponding to those of a portion of an associated line conductor, means for energizing the compensator proportionally to the current in the associated line, and a polyphase relay responsive to the combination of the derived voltages and the voltage or voltages across the compensator or compensators. Fig. 4 shows an arrangement responsive under phase-to-phase fault conditions and comprising potential transformers PT connected to the relay terminals through impedances ZBP each of which is a replica of the line impedance out to the desired reach or balance point of the relay. The impedances ZBP are energized from current transformers CT so that the voltages produced across the impedances subtract from the voltages of the potential transformers, relay operation occurring when the former voltages are greater than the latter voltages. In Fig. 11, an arrangement responsive to threephase faults has only one " compensator," i.e. the impedance 1.5ZBP, energized from a single current transformer CT. The Complete Specification describes and shows many variants of these two basic arrangements. It also describes and shows protective systems in which each zone of a three-zone system is provided with one of each of the above arrangements.
