Abstract :
Wide and narrow band partial discharge measurements performed on an oil-impregnated paper bushing indicate the presence of discharge pulse bursts, which are similar to those observed in dielectric liquids. Each pulse burst is detected as a single pulse by the charge integrating circuitry of conventional narrow band discharge detectors
