Significance of Condition Monitoring of Electrical Equipment in Transmission & Distribution System

The prime objective of any utility is to reduce number of breakdown and failures of equipments installed in their network as it directly impact the availability of the system. Top management officials are increasingly concerned with their abilities to keep their equipment working at peak performances. This poses the challenges of proper maintenance and upkeep of the equipments, extending equipment life cycles, maintaining and improving efficiencies, decreasing unscheduled downtime, planning for the unexpected failures – and all this while decreasing maintenance costs.

This paper provides information about Significance of Maintenance on Reliability & Availability of Electrical Equipment in transmission and distribution system. As quality and behaviour of the equipment is not uniform, the information presented here is to be utilized as guidelines and each Utility may suitably modify the maintenance procedures according to their need and experience if so required.
