It is performed in AC or DC with voltages varying from some hundred volts to several tens of kilovolts.
交/直流电压，电压几百伏到数万伏可调。
It monitors from 1 to 150 Amperes and switches up to 135 volts AC or DC.
它可以监测从1到150安培的电流，且能转换最高135伏的交流或直流。
When the DC waveform tries to drop back toward zero, the line voltage becomes less than the 20 volts the capacitor has been charged to.
当直流波形试图回落到零，线电压小于20伏的电容被充电到。
