超前电流 meaning in Chinese

leading current

3 in the sinusoidal alternating circuit that only contains an inductor , the voltage across the inductor leads the current through it by 90 , and they have the same frequency
在只含有电感的正弦交流电路中，电压超前电流90 ，且它们具有相同的频率。
The product adapts to single - phase asynchronous motor and three - phase asynchronous motor , which is supplies with single - phase power and the frequecy is blew 100hz . it is specially used for supplying leading current for elecrtomtor , and then the electromotor is actuated with the adeqate moment consequently . and when the electromotor runs smoothly , the capacitor will disconnect from the circuit . the product possesses stable capacity and long relative runtime
1 .用途及特点适用于100hz以下单相异步电动机和单相电源供电的三相异步电动机，专门用于向电动机提供超前电流，使电动机获得足够的力矩而起动。
