MAINTENANCE
Preface
Switchyard condition, both indoor and outdoor, demands economic use of resources, high reliability and quality of supply to consumers. The importance of switchyard maintenance cannot be overemphasized. Tenaga Switchgear Sdn. Bhd. has the necessary expertise at its disposal to ensure switchgear remain in good condition.
Scope Of Maintenance
The scope of maintenance service cover a wide range of makes both Gas Insulated
switchgear and outdoor switchgears. This includes the following areas:
- Circuit Breakers up to 275kV
- 33kV / 11kV Transformer Tail Circuit Breakers
- Busbars
- Isolators
- Conductors
- Bushings
- Lightning Arrestors
- CT & CVT
- Earthing Systems
- Checking and Rehabilitation of any flashover damages
The objective of good maintenance practices are as follows:
- improved safety of operation
- significant reduction of maintenance time and costs
- improved reliability of operations and protection
- adapt and optimize changes incorporated in rehabilitation of switchyards
Maintenance is divided into two categories : which are maintenance of circuit breaker & maintenance of ancillary equipment such as Isolator, CT, VT & etc.
