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。
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。
