Maintenance and Routine Testing
Many owners of HV plant assume that if they maintain their HV plant and test the oil for DGA then they are performing all the necessary maintenance to ensure a long and trouble life from their network. It is important to remember that protection relays and auxiliary devices can sometimes fail, their calibration may drift and wiring could loosen with vibration. It is imperative that owners implement routine testing and maintenance of the secondary systems, to ensure that under fault conditions, the protection can operate to its optimum and clear the fault in the required time to maintain system stability and minimise expensive outages and damage.
Megavar performs comprehensive maintenance and routine testing for all types and vintages of protection and control apparatus to ensure that trips, alarms and controls function they way there designed to. Our services include:
- Secondary injection
- Relay and transducer calibration
- Maintenance of mechanical relays
- Alarm checks
- Trip checks
- Burden measurements
- Wire tightness checks
and of course we present the client with a comprehensive report of thetest results for the equipment tested, detailing any recommendation, faults found and corrective works undertaken.
Megavar assists its clients to develop a maintenance schedule that suits their requirements and can schedule the testing in accordance with the shutdown cycles of the clients site. Out testers have extensive experience in distribution and transmission networks as well as generation plants, mine sites, refineries and heavy industrial plants.
