    In practice two types of impulse voltages can occur (i) full wave and (ii) chopped impulse wave.If the lightning surge travels along the transmission line,it results in full wave impulse voltage reaching to transformer.Whereas if the surge voltage causes a flash over just before reaching to transformer it results in chopped impulse wave. The full…
