Partial discharge testing eliminates cable replacement

Article Abstract:

Partial discharge (PD) measurements have been successfully applied to cable analysis after proving their worth in gas-insulated substations and transformers. Weak sections in cable circuits are located by means of a diagnostic test method which measure PDs of sufficient energy levels.
