Filed: 1989-08-17
Abstract: PURPOSE:To test a ground circuit only by zero-phase currents by using the zero-phase currents of arbitrary one circuit as reference vector and deciding the presence of significance regarding phase difference with the zero-phase currents of residual circuits in the multi-branch switch of a power distribution system. CONSTITUTION:Outputs A'-F' from ZCTs at every circuit of a multi-branch switch are input to an arithmetic section through auxiliary transformers AXT, filters F, sample-and-hold sections SH, a multiplexer MPX and an A/D converter A/D. One circuit is used as a reference circuit and phase between zero-phase currents is compared through the system of the sum of products in the arithmetic section. That is, when the arithmetic result of the sum of products takes a negative value, significance is determined, and the circuit is decided to be a fault circuit when the number of circuits taking a negative value is one. When the number of circuits taking the negative value is the number of circuits minus one, the reference circuit is decided to be the fault circuit. Accordingly, a ground circuit can be tested only by zero-phase currents.
