  • Effects of MV and HV cable capacitance on operational

    Aug 03, 2018The cable charging effect results in the capacitive current flowing in the cable under loaded and unloaded conditions. With high enough value of capacitance, the charging current can exceed the rated current. Underground lines have many times the line charging current that an overhead line, depending on line voltage.
