Many power equipment failures and short-circuit incidents are preceded with incipient faults. Such faults often leave unique ?marks? on the voltage and current waveforms. In recent years, engineers and researchers in the fields of power quality, power system protection and equipment condition monitoring have all recognized that such unique ?marks? or waveform signatures can be used to detect the occurrence of incipient faults. Thus a proactive approach to power system protection may become a reality.

This webinar will present the state-of-the-art developments in the area of incipient fault detection, primarily from the perspective of power quality (PQ) monitoring. PQ monitors are probably the most versatile waveform recording devices and PQ analysis is essentially waveform analysis. As such, PQ monitoring platforms may represent the easiest way to realize ?incipient fault detection on a budget?. The webinar will also explain a recent technical report completed by the PES WG on Power Quality Data Analytics, PES-TR-73: ?Electrical Signatures of Power Equipment Failures?. The webinar will further discuss, frankly, the limitations of existing techniques and the various paths to move forward in this important direction.
