Abstract :
PD monitoring is recognized today as an essential tool for condition based maintenance strategies for many HV equipment. This paper summarizes the experiences of a PD online monitoring device for power transformers and rotating machines which has been introduced in the market more than five years ago. The concept and design of a typical monitoring system is presented. Some experiences and problems with installed systems are discussed. Finally certain new methods are illustrated and an outlook for future trends and developments in PD monitoring is given.
