1.静电计式测量仪的初级变换器电流的静电计测量法的原理是测量待测电流产生的电压。作为电流一电压的初级变换器,可用电阻器、电容器或电流与电压之间有对数关系的元件(二极管)。在静电计式电流测量仪中,自动补偿测量法占多数。初级变换器按在静电计放火器的负反馈电路中,放大器的输出电压经过初级变换器产生的补偿电流,
1. Electrostatic meter type primary current transformer electrometer measurement principle is to measure the measured current generated voltage. As a current-voltage primary converter, a resistor, a capacitor, or an element (diode) having a logarithmic relationship between current and voltage can be used. In the electrostatic meter current meter, automatic measurement of the majority of compensation. Primary converter according to the negative feedback circuit in the electrometer fire arrester, the amplifier output voltage generated by the primary converter compensation current,
