Field experiences using Radio Frequency Scanning (RFS) to detect partial discharge in bus duct and metal clad switchgear of electrical generating and transmission substations
Abstract:It is well known that Partial Discharge (PD) is the latest stage of almost all failure modes in electrical insulation. Early detection of this phenomenon can avoid catastrophic failures of electrical equipments installed on transmission, distribution and generating stations. In this paper, two practical experiences using Radio Frequency Scanning (RFS) to detect partial discharge in electrical equipments are described. PD occurrence in two of three phases of a 13.8 kV air isolated bus duct was detected using RF… Show more
