Title: Marking device of parallel multi-circuit ground-fault point
Inventor: EMURA TOKUO
IPC: H02H3/40
Filed: 1983-08-12
Abstract: PURPOSE:To mark exactly a distance to a fault point even in case of a circuit of three circuits or more by marking a distance to the fault point from a zero- phase current of each circuit of a high resistance ground system parallel multi- circuit transmission line. CONSTITUTION:Current transformers ICT-nCT provided on the own end side of each circuit 1L-nL provided between each bus A, A' of the own end side and the other party end side detect zero-phase current I01-I0n of each circuit. This current is inputted to a sample and hold circuit S/H through auxiliary transformers 1AX-nAX and a low-pass filter LPF, sampled 12 times in one cycle and held. Each held value is inputted to a storing circuit M and an arithmetic circuit C through a multiplexer MPX and an A/D converter. The arithmetic circuit C operates il as shown by the expression ( I ) with regard to an il circuit in the circuit with a sampling data, and also operates a marking Li of a faulty circuit by the expression II. In this way, there is not error contained in the arithmetic expression of marking theoretically, and the marking can be executed with a high accuracy.
