Customer’s demand
|
|
Our customer is looking for a 3-phase transformer for application in a 50 kW inverter. The transformer is supposed to be part of a bidirectional 4-phase inverter. Both primary and secondary need a star connection with outwards lead star point. The power should be transferable in both directions. Every phase, this includes the star point, should be able to cope with only one third of the total power, when operated monophasic.
|
|
Solution
|
|
We construct an adapted three phase transformer with adjusted primary- and secondary winding. As vector group YNyn0 is used.

Technical data

Power: 50 kVA Primary: 3 x 400 V Secondary: 3 x 400 V Current: 80 A Weight: 300 kg Vector group: YNyn0

Customer’s demand
|
|
Our customer is looking for a 3-phase trasnformer to perform power measurements with in phase voltages. The phase delay caused by the existing three phase transformer with 3 x 400 V output should be reversed by 150°. A transformer with small power is enough for our measurement setup. The device should be mounted in a housing with 4 mm sockets.
|
|
Solution
|
|
We develop a three phase transformer with adjusted primary- and secondary voltages. The chosen vector group Dy5n as well as the winding setup make it possible to operate the transformer forward and backwards and thus to reverse the phase delay of the existing three phase transformer.
