High current transformer without unbalanced load

BV 1606001

Customer’s demand

We are in need of a single-phase high-current transformer which can be three-phase connected without any unbalanced load. The current should be at 500 A and has to serve as resistive heating. Temporary overload should be possible. Secondary sided current and voltage should be displayed.


A high-power transformer which is able to distribute the load three-phase to single-phase on the three primary coils even by using a special vector group. To cope with overload thermal driven fans are mounted. To customer’s demand, the connections are made as high current cables.
