This paper gave a result that the majority faults of HV overhead transmission lines focus on cablejunction by analyzing the causes of the damage of electric power cable.
Instructive analysis on power cablejunction faults is carried out and an algorithm for indirect on line measuring of cablejunction resistance and insulation aging is proposed.
