In power engineering, transformers are used to connect the various voltage echelons of the power grid to each other. In transformer stations, electricity from the regional distribution grid with a medium voltage level of 10 to 36 kV is transformed to supply power to low-voltage end customers in the local grid.

The heart of a transformer station is the transformer itself which also requires protective equipment.

By carrying out hands-on measurements and fault simulations with the training system, it is possible to gain an understanding of these complex systems in the classroom.
