Lightning Withstand Level的意思|示意

These new methods and measurements improved the lines' lightning withstand level in some degree.

这些新方法和新措施的采用在一定程度上提高了线路耐雷水平。

Installing line ZnO surge arresters is a very important countermeasure to improve the lightning withstand level of transmission line.

采用线路用避雷器是提高输电线路耐雷水平十分重要的措施。

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。

But the invasion of lightning surge may lead its failure due to its low voltage withstand level which may affect the normal service power system.

微机保护系统是电力系统的重要组成部分，但由于其耐压水平低，雷电波侵入电源系统时易导致设备的损坏，严重影响了电力系统的正常运行。
