Ensure the Safety and Reliability of Your High Voltage Transformers

with Expert Oil Sampling Services from ENWCML

At ENWCML, we understand the critical role that high voltage transformers play in delivering power to businesses across the UK. That’s why we offer a comprehensive range of oil sampling services to our COMA customers to help you ensure the safe, reliable, and efficient operation of your transformers with testing carried out via an independent provider.

Regular oil sampling is essential for…

Identifying potential problems early

Our oil sampling services, conducted as part of your PPM inspection programme, can detect the presence of harmful contaminants, such as moisture, dirt, and dissolved gases, which can lead to transformer failure. Early detection allows you to take corrective action before a costly outage occurs.

Monitoring transformer health

By tracking changes in the oil’s properties over time, we can help you assess the overall health of your transformers and identify any developing trends that could lead to future problems.

Optimizing maintenance

The insights gained from oil sampling can help you optimize your maintenance schedule, ensuring that your transformers receive the care they need to operate at peak performance.
