Overvoltage Occurrence Due to Ferroresonance Phenomena During The EHV Cable Feeder Charging


Abstract
EHV cables have higher capacitance and a larger current, which increases the possibility of overvoltage occurrences during the charging. A 400kV EHV cable experienced a long-duration overvoltage incid... see more
