Abstract :
A fast partial discharge (PD) measurement system is described, which employs analog as well as digital signal processing to achieve high sensitivity and discharge pulse resolution with low spectral distortion. Data on apparent charge, time of pulse occurrence and instantaneous applied voltage are stored in memory for subsequent information retrieval and treatment. The PD measurement system is designed to provide an integrated response to rapid rise time pulses of 1 to 2 ns, with suitable filtering added to reject extraneous noise.
