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.

Solution

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.
