Vacuum on-load tap-changers
Our new generation of tap-changers uses the latest vacuum interrupter technology. This design philosophy allows the arcs during load commutations to occur in vacuum interrupters and not in the tap-changer oil. This greatly reduces the need for maintenance and creates the potential for using environmentally friendly insulating fluids.
Hitachi Energy offers a full range of products for both high voltage and low voltage regulation. Our tap-changers are paired with robust, dependable motor drives that are configurable to meet a wide range of environmental conditions and customer specifications..
