Abstract
Protection from grounding of the stator windings of generators that operate on collecting lines is now carried out by means of a line transformer of zero sequence current with magnetization (LTZC). Owing to the high imbalance current is is not possible to carry out sensitive protection that reacts to a current of industrial frequency. Solving this problem is possible by applying a control current with a frequency of 25 Hz to the generator voltage circuit, since in this case frequency detuning from the imbalance current is possible. This article describes development of a protection based on this principle.
