Abstract
A matched filter approach is proposed for the location of a partial discharge within a winding. The approach is very general and does not need isolation of the capacitively transferred components. Simulations are performed on a lumped parameter model of a layer winding to prove the feasibility of the method. Experiments are also performed on a layer winding in order to validate the method. It is possible to extend the method to the determination of location of PD during impulse tests.
