对地电压 voltage to earth
voltage to ground
- 任何被测试对象对地电压,包括直流和交流,不能超过250V。
Do not apply more than 250V(AC or DC) between any input and earth ground. - 当故障发生在3相4线系统中的一相时,其它两相的对地电压就升高(约升高20%)。
When a fault occurs on one phase of a 3-phase, 4-wire system, the other two phases rise in voltage relative to ground (about 20%). - 本产品适用于对地电压交流不超过200V和脉动直流峰值400V电焊机用二次侧接线及连接电焊钳。
This product is suitable for the voltage t0o the groubd not more than 200V and its pulsating current value 400Vwelding disecnngcting line and so on。
