low voltage level

基本解释

Excessive common-mode current can significantly affect low-level voltage measurements.
过大的共模电流能够严重地影响低电平电压的测量。
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。
Load-center unit substations, where the power is transformed from the medium voltage level to the low voltage level, are also powered from the auxiliary buses.
将电压从中压变至低压的电厂负荷中心单元变电站，也从厂用母线获得电源。
