Lightning stroke is one of the important reasons that result in power failure. Tower lightning surge response performance is the important factor deciding transmission line lightning over-voltage.
雷击是导致输电线路故障的重要原因之一，杆塔的雷电冲击响应特性是决定输电线路雷电过电压的重要因素。
There are two indexes to evaluate the power line performance on preventing lightning strikes: the one is the lightning trip-out rate, the other is the lightning withstand level of the power line.
为了合理设计输电线路的耐雷水平及雷击跳闸率，通过理论推导，修正了现有规程的输电线路耐雷水平计算公式。
There are two indexes to evaluate the power line performance on preventing lightning strikes: the one is the lightning trip-out rate, the other is the lightning withstand level of the power line.
衡量线路防雷性能优劣的重要指标有两个：一是线路雷击跳闸率； 二是线路耐雷水平。
