Abstract

Partial discharge (PD) pulses are recorded with an analyzer connected to a PD detector. The analyzer presents PD data as distributions that are used to interpret the PD phenomenon. The paper describes results of ageing experiments on oil impregnated pressboard samples subjected to PD measured with a narrow band detector and analyzer system. The main focus of the paper is on instrumentation related with narrow band detector and analyzer. A detailed response study of the narrow band detector is carried out to understand its behavior with pulses appearing with different repetition rate. The paper discusses characterization of PD distributions for meaningful interpretation.
