EUT TRANSFORMERS

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. 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.

Training contents:

• Transformer equivalent circuit diagram
• Multiphase transformer operating at no-load and short-circuit
• Multiphase transformer with ohmic, inductive and capacitive load
• Parallel operation of multiphase transformers
• Current distribution for different vector groups
• Determining zero impedance
• Investigating the transformation ratio
