This thesis proposes a technique for identifying deteriorated or contaminated electrical equipment. The technique uses the harmonic components of demodulated radio frequency (RF) and ultrasonic emissions to detect partial discharge (PD) events from faulty or contaminated components. The technique uses the sum-of-squares of the magnitudes of the first five 60-Hz harmonic components of the demodulated RF signal to detect the presence of faulty power system components. A parabolic acoustic noise detector captures ultrasonic emissions to pinpoint the physical location of the faulty power system component or components that causes the detected RF emissions. The proposed technique is capable of detecting all emissions detected, as well as others not detected, by the current industry standard – The Exacter Trigger. It is also more compact and portable, and it uses less data, requires fewer computations, and consumes less power. Single-chip digital signal processor implementations of the proposed technique are extensively validated via laboratory and field tests.
