Repair and Refurbishment of HV. Current and Voltage Transformers, including installation and on-site testing and commissioning

Repair and Refurbishment Service

We offer a complete range of facilities and expertise to repair, modify and refurbish high voltage Current Transformers/Voltage Transformers up to 33KV (66KV).

Each transformer would be checked for ratio and accuracy, insulation tests would then be carried out and in the case of oil or compound filled units, the medium would be replaced with new. All metalwork would be stripped, primed and repainted where possible and contact surfaces retinned. After final routine test to the relevant standards, the transformer would be ready to return into service.

This solution is a quick, economic alternative to the sometimes costly and lengthy replacement of time expired equipment. We can also offer cast resin Voltage Transformer units up to 11 KV to replace existing oil units and upgrades from 3-limb to 5~limb arrangements where breakers are part of a switch gear retrofit exercise, for both obsolete and more modem switch gear types.
