Synergy in energy: T-Sync™ tap-changers

Achieving top performance in the face of tomorrow’s energy demands is a big challenge. Hitachi Energy is helping our customers to meet that challenge. As a world leader in transformer components, we provide a unique combination of tap-changer technology, deep expertise, and support that adapts to our customer’s needs. Because it is only by working in sync that we create synergy in energy.

It is a partnership to get the best performance out of assets over their entire lifespan, including training and support in self-maintenance. While open design means that our technology easily integrates with existing assets, choosing from our comprehensive vacuum and oil tap-changer portfolio could not be easier with our Compas selection tool.
