SUPERSONIC WAVE ANALYSIS METHOD FOR POWER FACILITY DIAGNOSIS AND AN APPARATUS THEREOF, WHICH CAN DETECT A BREAKDOWN SPOT ACCURATELY BY MEASURING AND ANALYZING A SUPERSONIC SIGNAL

摘要

PURPOSE: A supersonic wave analysis method for power facility diagnosis and an apparatus thereof are provided to diagnose distribution line efficiently by measuring an ultrasonic signal from a power device detected with high frequency wave noise signal and detecting facility in poor condition.;CONSTITUTION: A signal processor(208) changes the received ultrasonic signal into the voice signal. Only signal related to the power frequency is extracted, even when the external noise exists. A signal processing unit can detect the ultrasonic signal emitted in the fault electric power facilities.;COPYRIGHT KIPO 2010
