Let our maintenance team assist you in planning a regular programme of inspections and record keeping to keep your plant in good working order. Such a programme will significantly reduce downtime in the event of failure and will drastically reduce the likelihood of you having to repair transformers in the first place.

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.

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.
