Identification of faults and disturbance induced by de-icing for overhead transmission line based on the permutation entropy
The ice-shedding may induce isolated ground wires temporary grounding during de-icing, which can cause the protective relay of direct current de-icing devices triggered frequently and unnecessarily. After analyzing the circuit of the grounding isolated ground wire, the conclusion can be obtained tha...
