Presents an equivalent circuit for a lightning stroke to estimate the magnitude and waveshapes of currents and voltages on power transmission system components due to lightning strokes. Results for strokes to towers, mid-spans of overhead ground wire, ground and line conductors are presented. For these cases times to front of voltages are about 1 μs and that for currents are in the range of 8 to 10 $\mu s$. Crest currents are as high as 100 kA whereas voltages are upto 3 MV. Arrester currents can go as high as 1400 A with a front time of the order of 15 $\mu s$, while the arrester voltages are substantially rectangular lasting anywhere upto 60 $\mu s$.
