The prediction of surge attenuation and distortion by corona on overhead lines is relevant to both insulation design and overvoltage protection. The authors describe a computational procedure to obtain the corona capacitance from the line geometry, thus avoiding the need to impulse-test full-scale line models. The simulation of surge corona loss by a switched capacitor with constant and voltage-dependent capacitance representations is discussed. Surge attenuation and distortion for positive and negative impulse voltages applied to transmission lines are computed and compared with published measured voltage waveshapes, with satisfactory results
