Abstract
Diagnostics by partial discharge measurement is a modern diagnostic method for determination of the state of insulating systems of high voltage machines and equipment. In the High Voltage Laboratory of the Czech Technical University in Prague was developed the complex measuring and evaluating system for partial discharge measurement. Unfortunately, the main problem of discharge activity measurement in practice is in electromagnetic disturbance. This article is focused on the removing this disturbance from measured data. Great problems in the evaluation of partial discharge data is in various sorts of interferences.
