When operating with high voltage equipment the use of Partial discharge (PD) detection equipment is necessary.
Partial discharge is a localized dielectric breakdown of a small portion of a solid or liquid electrical insulating system under high-voltage field stress, which does not bridge the space between two conductors. If left unattended, partial discharge often leads to a failure of the electrical insulating system.
To detect PD in the early stages or to determine source location periodic diagnostic PD measurements are recommended.
Reliable and long-term operation of high voltage equipment can only be assured by PD prevention and detection.
