Introduction Of Multi Winding Transformer
Jun 11, 2018

The so-called multi winding voltage transformer, that is, is a transformer with one primary winding and multiple two winding, such as a common voltage transformer with a basic two winding and a residual voltage winding (also called zero sequence voltage winding). When the system is normal, the three-phase voltage is symmetrical and the output voltage of the remaining voltage winding which is connected to the opening triangle is close to zero. At this time, the transformer is operated by the double winding transformer. When a single-phase grounding fault occurs in the system, the three-phase voltage is asymmetrical and the residual voltage winding has zero sequence voltage output. At this time, the transformer is operated by three winding transformers. Some voltage transformers have two two windings on the two side (one for measurement). The other is for protection) and a residual voltage winding, so in case of fault, the transformer may run in the four winding state.
