<p><P>PROBLEM TO BE SOLVED: To provide a conductor monitor for a power receiving and distributing facility capable of efficiently monitoring individual bus-bars by automatically setting a thermal model of the bus-bar. <P>SOLUTION: The conductor monitor for the power receiving and distributing facility includes: a bus-bar surface temperature measuring means 11 installed on the power receiving and distributing facility; an ambient air temperature measuring means 12; a bus-bar current value measuring means 13; an arithmetic unit 20; and a memory device 30. After the bus-bar temperature, a current value and the ambient air temperature in a normal state of the power receiving and distributing facility are measured to calculate reference parametersαr,βr specifying the thermal model of the bus bar, the bus-bar temperature, the current value and the ambient air temperature during operation of the power receiving and distributing facility are measured to calculate operation parametersαx,βx specifying the thermal model of the bus-bar, and the abnormality determination of the bus bars is performed by comparison between the operation parametersαx,βx and the reference parametersαr,βr. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
