Abstract

The lightning performance of overhead transmission lines is greatly affected by backflashover, that is, flashover of line insulation due to fast front overvoltages caused by lightning strokes terminating to towers or shield wires along line spans. One of the parameters affecting the estimated backflashover rate of overhead transmission lines is the minimum lightning current causing backflashover. In estimating this critical current, the lightning stroke location along the span is usually disregarded. Actually, the backflashover rate of overhead transmission lines is most commonly estimated based on the critical current corresponding to lightning strokes to transmission towers. The fact that lightning strokes terminate to shield wires along the span is considered indirectly by using a multiplier coefficient (span factor) of 0.6; however, this coefficient is expected to depend on the several influencing factors. In this study the minimum backflashover current of 150 and 400 kV double-circuit overhead lines of the Hellenic transmission system is estimated through ATP-EMTP simulations considering the lightning stroke location along the span. It is shown that the lightning overvoltages stressing line insulators decrease with increasing distance of the lightning stroke location from the tower, taking the lowest values at midspan; this behavior is due to the lower current flowing through the tower for midspan strokes. The minimum backflashover current increases with increasing distance from the tower; this is less pronounced for relatively high ground resistance values. The ratio of the total backflashover rate of the overhead lines to the backflashover rate for strokes to tower only (span factor) is found to vary between approximately 0.5 and 0.9, depending on tower ground resistance and transmission line geometry and insulation level. Thus, the span factor may take values significantly higher than the commonly used value of 0.6; this may lead to underestimating backflashover rate, especially for overhead lines with relatively high ground resistance values.
