Present procedures for evaluating full and chopped lightning impulse voltages in accordance with IEC 60060-1:1989 [1] are only an approximation of the physical behavior of the insulation and do not always give reproducible results for impulse waveforms with superimposed oscillation and overshoot. The results of a recent study have provided technical basis… CONTINUE READING
