The assessment and management of older oil-filled switchgear

摘要

Older oil-filled switchgear installations require careful management if reliability problems and hazardous situations are to be avoided. Central to the effective management of switchgear populations is an understanding of the deterioration mechanisms and the actions that can be taken to minimise failures. In addition, the adoption of an assessment methodology, including appropriate diagnostics, provides sound information on which to base decisions on switchboard replacement.
