ARCING SOURCE POSITION DETECTOR

摘要

An arcing source position detector which can identify an electrical fire indication due to electrical arcs occurring in the electrical wiring, facilitates the tracking and detecting an arcing source position, and providing audible alarms highly correlated with the high frequency noise signal due to the arcs when arcs are being generated. The magnetic field sensor (10) senses the high frequency magnetic field generated by the high frequency noise due to arcing occurring in an electrical wiring and outputs a detection signal. The preamplifier (12) preamplifies the detection signal to output a preamplified signal. The filtering means (16) filters the preamplified signal to selectively pass frequency components in a predetermined frequency band and output a filtered signal. The sound converting means (22) converts the filtered signal into sound. The displaying means (26) visually displays the level of the filtered signal.
