Waveforms of induced voltage from lightning strokes to a high stack of the power plant have been measured simultaneously with the current waveforms of lightning stroke to the stack since December 1980. This paper shows the lightning stroke current waveforms and the lightning induced voltage waveforms over a 4 year period from October 1984 through March 1988. The combination of polarities for waveforms of lightning induced voltage and lightning stroke current is indicated below: (a) Positive induced voltage in response to negative lightning stroke current...Sixteen cases. (b) Negative induced voltage in response to positive lightning stroke current...Two cases. The induced voltage waveforms generated on a distribution line were calculated by means of improved numerical analysis which took the height of a stack of the power plant into consideration. The calculated results agree better with the measured waveforms than those by means of an earlier analysis method. It is clarified that bipolar induced voltages are not produced by usual lightning stroke currents.
