TRANSFORMER MAINTENANCE
Our approach to routine maintenance on Transformers is focused around creating a bespoke maintenance programme which meets our client’s business needs and expectations.
We can offer a transformer maintenance service as a once off service or, most usually, as part of our maintenance contract.
Our maintenance regimes follow manufacturer’s recommendations as well as legislative requirements. We advise our customers to undertake full intrusive maintenance of liquid cooled transformers once every 4 years and where possible we recommend that air cooled transformers be shut down and maintained annually.
We also advise our customers to take oil samples from oil cooled transformers annually, which we send to our associate laboratory for full analysis.
These are our minimum basic recommendations, this can alter dependent on the site survey taking into account the site layout, environmental conditions and customer requirements.
All such transformer maintenance and inspection works are covered with customer written reports that detail our findings and recommendations.
We can also develop specific and bespoke maintenance regimes, which work in tandem with business and operational needs.
Our Transformer Maintenance Service includes full maintenance of:
Air cooled Transformers
- In particular dust removal from the enclosure
- Partial discharge testing on the HV side
Oil cooled Transformers:
- Breather replacement
- Partial discharge testing on the HV side
- Taking oil samples – an oil analysis report will be issued thereafter.
- Replacement of oil when and if required is undertaken in conjunction with our approved specialist supplier thus ensuring all environmental legislation is adhered to during this operation.
