Case studies
Onsite transformer repair
Our team attended our client's site to remove a three phase 750kVa transformer; which required one of the phases to be rewound. This was achieved with 5 day turnaround to ensure production was up and running as soon as possible.

Onsite transformer maintenance
Our client had 9 power transformers onsite and required our team to carry out a full survey and inspection. This included oil sampling and visual inspection and issuing a full report. The report highlighted critical maintenance was required and was carried out to ensure our client had no downtime.

Transformer test and repair
We enjoy a strong relationship with the MoD and repair a wide range of transformers for use within a military application; including isolation transformers. These transformers range from 1kVA up to 150kVA.
