A DIAGNOSTIC METHOD FOR A DANGEROUS CONDITION OF ELECTRICAL POWER EQUIPMENT USING ABNORMAL SIGNALS

摘要

PURPOSE: A method for diagnosing a dangerous state of a power facility using an abnormal signal is provided to diagnose whether the power facility is in a dangerous state using the abnormal signal generated in the power facility. CONSTITUTION: A measurement system installed in a vehicle includes a spectrum analyzer(320) to analyze signals of various kinds and amplitudes received through a HFPD(High Frequency Partial Discharge) antenna(310). A GPS antenna(330) receives position information data as to measurement position. A GPS unit(340) tracks the measurement position using the position information data received through the GPS antenna. An infrared ray camera(350) checks the position of an abnormal signal more accurately. And a computer(360) judges the existence of the abnormal signal from data being output from the spectrum analyzer and makes an alarm when it is judged as an abnormal signal.
