Digital measurement of partial discharges in full-sized power capacitors

Abstract

Partial discharges measurements in power capacitors have been carried out using a digital technique. The advantages of the use of this digital technique are discussed. The digital equipment design is presented. Test results on industrial all-film power capacitors with high capacitance values are presented together with measurements of the PDIV before and after the endurance tests.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
