The lightning trip-out rate of Shandong province transmission line meets the demand of ministry regulation and it is lower than the average trip-out rate of transmission line in China.
该省线路雷击跳闸率满足部颁规程要求，在全国输电线路中雷击跳闸率也是较低的。
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。
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。
