It uses the straight line zero dimension processing method to solve the problem of the index unit and the magnitude. 采用直线型无量纲化处理方法来解决指标的单位及数量级问题。
The accuracy CT and precision resistor convert the current flowing in the power line into the voltage signal. The voltage signal is modulated and transferred to the optical pulse, which is transmitted to the low potential area through optical fiber and demodulated by signal processing unit. 高压线路的待测电流经小型高准确度CT和精密电阻变为弱电压信号,再经调制电路和发光二极管转换为光脉冲信号,通过光纤传输到低压端进行信号解调和处理。
