About Us

Ferranti On-Load Tapchangers have been supplied worldwide for over 60 years. The quality of the Ferranti transformer tapchanger is such that many of the earliest manufactured units are still in operation giving excellent service today.

The "Ferranti" mark is recognised globally as one of the most successful power industry products. Our range of Ferranti Tapchangers have been operating successfully for over 60 years and with our help in the form of repair, service, maintenance, refurbishment, technical advice and the supply of genuine Ferranti spare parts and service kits, there is no reason why our Ferranti Tapchangers should not continue to give excellent service for many years to come.

Ferranti Tapchangers is part of the Fundamentals Group of companies.

Fundamentals exists to solve problems and their products and solutions have been improving the health and performance of the electrical grid for over 25-years.

The invention of TAPP (Transformer Automatic Paralleling Package) and development of the SuperTAPP relay range established Fundamentals as experts in voltage control. The acquisition of Ferranti Tapchangers and legacy GE Tapchangers (incorporating well-known brands such as Metropolitan Vickers, AEI, English Electric etc.), and the addition of products to the portfolio has resulted in a market-leading position for the company.
