There has been increasing application of on-line partial discharge (PD) based cable insulation condition monitoring among utilities worldwide due to the ability of on-line PD monitoring to allow incipient insulation faults to be detected and aged cable replacement program to be prioritised. However the application is also accompanied with a number of challenges. Data from on-line PD monitoring systems...
A power generating station in the United Kingdom has reported a number of in service failures in its 11kV single core Ethylene-Propylene Rubber (EPR) insulated cables. Several industrial companies have carried out on-site condition assessment to determine whether other insulation defects were present but no conclusive results have been found due to presence of strong background electrical noise. The...
Of the vast amount of MV cables in the UK, the majority was installed in 1950psilas and 1960psilas. With a design life 60-70 years, age induced degradation and failure of the UK MV systems is becoming increasingly prominent in the minds of plant owners and operators. In this paper, the authors discuss the business case for on-line PD monitoring vs. off-line and compare on-line vs. off-line PD monitoring...
The most important indicator of the health of electrical plant items is the condition of their insulation for which partial discharge (PD) test or monitoring has been widely recognized as one of the best tools. The strategic importance of plant in the transmission network, and its high replacement and refurbishment cost, has categorized research and development aimed at PD based condition monitoring...
