Abstract :
The optimum method for electrical partial discharge testing of large capacitors, including the effects of internal inductance, is determined. The results indicate that internal inductance does not adversely affect detection sensitivity if the detection impedance is made equal to the critical damping resistance. This has the advantage of providing a nonresonant waveform which can be detected in a near-optimum manner using a simple low-pass filter
