MAINTENANCE OF CONNECTORS AND DISCONNECTORS IN THE EHV SYSTEM

Abstract

Connectors and Disconnectors play a major role in the performance of extra high voltage (EHV) system. Failure due to the connectors and disconnectors leads to the shutdown of the whole system. Also this leads to heavy losses and inconvenience to the users. Hence the maintenance of the connectors and disconnectors is an important activity in the EHV system. Among the three types of maintenance such as Preventive maintenance, Predictive maintenance and Shutdown maintenance , Preventive maintenance improves reliability, reduces downtime and improves availability of plant and equipment. If we do not plan and perform the scheduled maintenance, it leads to forced outage due to fault or equipment failure. As far as EHV system is concerned, preventive maintenance plays a vital role, for which a thorough knowledge on the major parts of EHV components is mandatory. This article deals specifically with the EHV Power connectors and disconnectors in Major Power systems, right from design upto maintenance aspects. The modern trends using computers enable us to achieve better maintenance results.
