Abstract

PURPOSE: To make it possible to investigate rapidly and accurately short-circuit disconnection accidents by detecting a line short-circuit current in the distributing main line and by collating it with a high-tension line short-circuit current distribution graph, etc., generated previously.
CONSTITUTION: Special CTICT1WICT3 are used as short-circuit current detection means, and output-side coils of them are made into Y-connection and are connected to input terminals 1S, 2S, 3S and L of display SA through cable CA1. Display SA obtains detection outputs from current transformers ICT1WICT3, and displays digitally the current value with mag sign MS1 and displays the conductive phase with mag sign MS2 in case that the short-circuit current over a set value is flowed over regulation. These displays are collated with a high-tension line short-circuit current distribution graph, etc., generated previously, thus deciding the direction of the short-circuit accident occurrence section.
