arc-fault

基本解释

Fire accident can arise from low-voltage arc fault, and so it is necessary to detect arc fault.
摘要低压故障电弧有引发火灾的危险，所以检测故障电弧是必要的。
In our country,the resonant earthed mode is now extensively applied in the MV system.The expanding of instantaneous ground arc fault is effectively controlled.
在我国,谐振接地方式在中压电网得到越来越广泛的应用,谐振接地方式有效地遏制了电网中发生的各种瞬间接地电弧故障的发展。
Research on Detecting Low-Voltage Arc Fault
关于检测低压故障电弧的初步研究
Through studying the principle of dimmer and switch power supply, it was found that in some frequency points, by analyzing the phase of electric voltage and current it can tell if arc faults occur.
研究调光灯及开关电源的工作原理可以发现，通过分析回路中电压电流在某些频率点的相位信息，可以有效判别是否发生了故障电弧。
Combination fuse-switch( CFS) unit compartments shall be designed and type-tested for arcing fault containment where the energy level available to the input terminals of the compartment exceeds1,000,000 A2 seconds.
