This project sought to investigate the development of a vacuum bolton type tap-changer based on the existing AT type design, a bolt-on model widely used within UKPN with many advantages over the in-tank type. The project scope covered the design, manufacture, KEMA type testing and fitting of a prototype on a new transformer for field service.
The project was investigating development of a bolt-on vacuum insulated on-load tap-changer for power transformers, with a view to addressing the issues of high maintenance requirements and safety risks associated with of oil-insulated types.
