Abstract
An acoustic diagnostic system for detecting misalignment of switch blade contacts in power distribution systems is disclosed. In accordance with one embodiment of the present invention, the high frequency component of the acoustic signal generated by the make and break of electrical contacts in high energy power distribution equipment is filtered and demodulated to produce a waveform from which significant timing information is provided. A method for producing these waveforms is also disclosed.
