Pollution Flashover

Lighting is one of the important reasons of transmission line trip accident. For 330kV and above ultra high voltage transmission line, lighting flashover more frequently occur. To reduce tripping rate effectively and fundamentally, lightning over voltage level should be analyzed besides anti-pollution flashover. In this paper, a simplified equivalent circuit model of a 330kV overhead transmission lines is established. The lightning over voltage of the transmission is analyzed and calculated. Method to reduce the lightning overvoltage is discussed.
