Abstract :
Many kinds of partial discharge detectors are available, and many kinds of windings are adopted for EHV transformers, where propagation of partial discharge pulses is characterized mainly by series capacitance. The acoustic method is predominantly used for partial discharge location, because of the present scarcity of investigations on the electrical location method.
