Causes of Misoperation of Differential Protection of Transformer
The differential protection of the transformer is the main protection of the transformer, which is installed according to the principle of circulating current. It is mainly used to protect various phase-to-phase short-circuit faults that occur inside the windings of double-winding or three-winding transformers and their lead-out lines, and can also be used to protect single-phase inter-turn short-circuit faults of transformers.
