<p><P>PROBLEM TO BE SOLVED: To detect abnormality before an accident occurs for contributing to accident suppression by identifying an accident point of an electrical facility with sure and with high precision and limiting a supply failure range since isolation. <P>SOLUTION: A central processing part of a central monitoring/control device 2, upon operation of a protective relay at accident, obtains image information and temperature information, and temporarily identifies a monitoring region in which abnormality is detected. Based on the monitoring region in which image abnormality or temperature abnormality is detected and the protective range of the protective relay that has acted, a monitoring region in which abnormality is detected is identified, and a "turn-off" operation command for the device is issued. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
