Retrofitting
We are able to provide a total solution from initial appraisal and Tapchanger selection/design through to commissioning and the environmentally friendly removal and disposal of redundant equipment.

Many of our customers are recognising that retrofitting a new tapchanger can be a far more cost-effective solution than replacing the whole transformer.
Retrofitting

The Tapchangers we supply can be manually operated or fully automatic (including incorporation the new superTAPP SG). All new Tapchangers provided by us are fully bi directional thus allowing Distributed generation to be employed on the network with ease and reducing reverse power flow issues.
