Introduction: The project addresses replacing worn out tapchangers with new technology.

Objectives: The vacuum tapchanger project will attempt to fit a new technology tapchanger (Vacutap) to an existing asset which has a worn out tapchanger on a healthy transformer. The installation will be monitored on completion to assess the success of the project to aid future strategy on this type of problem. Cost savings will be delivered through achievement of extended asset lives with a reduced maintenance requirement.
