SUBSTATION MAINTENANCE

A well planned electrical substation maintenance assures reliable supply and reduction in failures. Many failures can be detected during the electrical substation maintenance routines, reducing the risk of significant plant downtime, and preventing future problems. The risk of a catastrophic failure can cost large time and money. The electrical substation maintenance involves periodic planned inspections, checking, testing and troubleshooting, to ensure the correct operation of all components and their interaction during the plant lifecycle. Typical inspection and diagnosis processes of the electrical substation maintenance includes, among others, transformers, breakers, protection relays, wiring and switchgear in general.

Each device requires different strategies. Implementing the right action at the right time will define different electrical substation maintenance procedures, whether time based, condition or reliability based. All of them must be supported by suitable testing tools.
