Analysis on switching overvoltage and suppression method of cable joint in 500 kV cable line

The breakdown accident of cable joint occurs frequently when the sheath overvoltage cable line is closed, but the cable joint is ignored or simply treated in the previous overvoltage simulation of cable system. To solve this problem, a joint equivalent impedance model is established for a 500 kV cab...
