Abstract

We have considered influence of surface complex of current noise on the operations of group protection from single-phase closing to the ground in circuit 6-35 kilovolt with isolated neutral terminal of mountain enterprise. We also have analyzed actions of noise operations of protections in different conditions of circuit: in normal state of working, when short circuit and single-phase closing to the ground arise on protectable connection.
