Three-phase voltage transformer

VBO3 is a three-phase voltage transformer with a transformation ratio of 1:2 and extends the range of application of a CMC up to 600 V (L-N). Main fields of application are tests in renewable energy plants and industrial networks with 400 V (L-N) [690 V L-L]. The transformer is designed for a nominal frequency of 50/60 Hz, the secondary voltage is load-dependent. In order to achieve good accuracy, the secondary voltage must be measured under load before carrying out tests. The transformation ratio determined in this way can be entered as a parameter in the hardware configuration of the Test Universe software. This makes it possible to work directly with the secondary values in the Test Universe.

With a CMC 430 (6 x 150 V), 3 x 600 V with neutral point can also be achieved using both voltage triplets.
