Early detection of impending failure in HV cable terminations

November 18th, 2019, Published in Articles: Energize, Featured: Energize

In a case study municipal substation, there has been prevalent failures of 88 kV cable terminations after 29 years in operation. All failed terminations were forensically investigated and the failure mechanisms within the cable termination were identified. Furthermore, an online data logging system had been installed in order to record the terminations operating parameters. In the present paper, firstly, the forensically identified degradation mechanisms are presented.

A review of the condition monitoring methods in the case study substation is then presented. A possible intelligent solution which allows the identification of impending failure is then discussed.
