The influence of zero-sequence impedance on power-frequency overvoltage of asymmetric eathing fault is researched though comparing surge impedance of different types of ACSR as ground-return wires. The power-frequency overvoltage is calculated in various conditions with OPGW. It is lower for the smaller surge impedance of ACSR consequently
parallel compensation capacity could be decreased to save the cost. The restrictions of using ASCR to limit power-frequency overvoltage are analyzed too.
