Paralleling of transformer
WebAug 26, 2024 · Parallel operation of three phase transformer is very common in three phase power generation, transmission and distribution. It is advantageous to use two or more Transformer units in parallel instead … WebMay 15, 2024 · But what would happen if these had different number of windings? On a transformer, there is only one Volts per Turn factor: V t / N = A e ⋅ d B / d t. So, for example, paralleling a 20-turn winding and a 100-turn winding is nothing different than paralleling a 20V voltage source and a 100V voltage source.
