Power Cable System is a vital asset in Electrical Power System. Now a days power cables are used in transmission and distribution of electric power at MV, HV and EHV levels. Reliability and availability of power supply depends greatly on insulation condition of the power cable system. Therefore, power cable asset management is vital for taking decision on future course of action to minimize capital expenditure, maximize reliability and avoid forced outages. In this paper, how to deploy power cable asset management is discussed using Health Index based on diagnostic test data.

Abstract


Power Cable System is a vital asset in Electrical Power System. Now a days power cables are used in transmission and distribution of electric power at MV, HV and EHV levels. Reliability and availability of power supply depends greatly on insulation condition of the power cable system. Therefore, power cable asset management is vital for taking decision on future course of action to minimize capital expenditure, maximize reliability and avoid forced outages. In this paper, how to deploy power cable asset management is discussed using Health Index based on diagnostic test data.
