Don’t take your transformer for granted!

Often, owners of power transformers neglect to maintain its moving parts – the tap changers.

As such, these frequently operate well beyond standard service intervals, risking unscheduled outages and costly losses.


Our tap changer services

We are proud to be one of very few transformer manufacturers to supply its own range of tap changers. In addition to this we also offer a full range of services to install, retrofit, service, repair and support tap changers.

Tap changer transformer installation

Every installation is carried out by our highly-trained service team. They follow a series of proven steps, from planning and methodology (including booking additional contractors or equipment such as cranes), pre-installation site visits, risk assessments and method statements to ensure full ISO 9001 compliance.

They then disconnect and remove the old unit, fit and connect a new BRUSH AT or AE tap changer, carry out the re-filling of oil and commissioning, and fit a bespoke adaptor throat fabrication.

Tap changer legacy support and retrofits

In addition to supplying and supporting our own range of tap changers we extend that support to legacy brands including Fuller, Hawker Siddeley, BRUSH and ATL.

To improve the efficiency and life of your existing transformer – and save you money on maintaining an aging system – we can also retrofit new tap changers with the minimum of fuss.
