Title: Improvements in and relating to electrical protective relay systems
Inventor: WARRINGTO ALBERT RUSSELL VAN C
IPC: H02H3/40
Filed: 1961-03-03
Abstract: 1,021,502. Protective arrangements. ENGLISH ELECTRIC CO. Ltd. Feb. 28, 1962 [March 3, 1961], No. 7782/61. Heading H2K. [Also in Division H3] To provide equal reach for all kinds of faults other than balanced three-phase faults, a dis. tance protective arrangement includes a comparator circuit 10 which is conditioned by switch means to compare, in the case of a multiphase fault, the amplitudes of the positive and negative phase sequence components of voltage signals and, in the case of a single-phase fault, the amplitudes of the positive, negative and zero phase sequence components of the voltage signals. The voltage signals are proportional to the phase-to-neutral voltages of the phases at the end of a protected section remote from the relay arrangement and are derived from voltage transformers 8, current transformers 4 and transactors 5, 6, the transactors constituting replica impedances of the protected section. A phase-sequence analyzer 9 applies the positive and negative sequence components V 1 , V 2  to rectifiers 12, 11 in the comparator circuit 10 and a transformer 15 applies the zero sequence component V 0  to a rectifier 14 in the comparator circuit 10 under single phase fault conditions so that a polarized relay 13 is energized by V 1 -V 2 -V 0 . When a multi-phase fault occurs, transistors 23, 24 are in a conducting state and short-circuit the secondary winding 15a of the transformer 15 to exclude the zero phase-sequence component V 0  from the comparator circuit 10, the relay 13 being energized by V 1 -V 2 . The transistors 23, 24 are controlled by an unijunction transistor 22 responsive to the output of a further comparator circuit 16 including rectifiers 17, 18. The rectifier 17 is connected by a transformer 19 to the analyzer 9 for energization by the negative sequence component V 2 . In the arrangement shown, the rectifier 18 is connected to a secondary winding 15c of the transformer 15 for energization by the zero sequence component V 0 . Alternatively, Fig. 2 (not shown), the rectifier 18 is energized by the positive sequence component V 1 . In both arrangements, on the occurrence of a multiphase fault with or without an earth fault, the relative polarities of the ends of a resistor 21 are as indicated and the voltage across the transistor 22 is such that transistors 23, 24 conduct, but in the case of a single phase-to-earth fault, the relative polarities are reversed and the transistors 23, 24 cease to conduct. A separate single phase distance relay may be provided to give protection under balanced three-phase fault conditions.
