Effects of corona on traveling waves

THE effect of corona on traveling waves is to retard any given point on a voltage wave above the corona threshold value by an amount proportional to the distance traveled. Thus the effect is equivalent to a reduction in velocity. If a linear circuit can be characterized by assigning to it a certain inductance L and capacitance C, per unit length, then a wave impressed upon such a circuit will propagate along the circuit with a velocity v, such that
