What is the function of generator transverse differential protection?

[McRuth]

Here are the functions of generator transverse differential protection: 1. Protection against stator winding inter-turn short circuits: The main function of generator transverse differential protection is to protect against inter-turn short circuits in the generator stator. It is used in situations where the generator neutral point has six outgoing terminals, and it can also protect against asymmetric short-circuit faults inside the generator. 2. Protection against inter-turn short circuits: Large-capacity generators generally consist of two parallel windings. Under normal conditions, the potentials of the two windings are equal, each supplying half of the load current. If an inter-turn short circuit occurs in any winding, the potentials of the two windings will no longer be equal, resulting in a potential difference that generates circulating current between the two windings.
