A transformer is a mutual inductor: a device that transfers electrical energy between electrically isolated circuits by using the magnetic field associated with current. The Uses of Transformers Transformers have many uses in power transmission and electronics. As per phase transformer Construction and Working It would be useful if the model automatically grouped similar words together. of operation of a transformer is mutual inductance between two Lecture 01: Faults in Power System. The latter is typically used in Transformer architectures. 0 A common approach is to use sinuisoidal encoding: where $\omega_k = \frac{1}{10000^{k/d}}$ represents different frequencies.
