The protection function library includes generators, auxiliary transformers, etc
And the differential protection of the generator group. Stator ground protection, package
Including 95% stator ground protection based on fundamental wave, third harmonic
Wave braking features 100% stator ground protection for both,
Among them, 100% protection uses a voltage differential method, with
High sensitivity, high safety. In addition, the device also
With loss of step protection, loss of magnetic protection, rotor ground protection
Protection, negative sequence current protection and so on.
