1000 amp primary current injection test system I.Working principle The HZDL-130 primary current injection test system measurement circuit includes a current measurement circuit. (voltage test can be added as required) with extended volt-ampere characteristics. The current measurement circuit includes micro-current zero impedance CT, program-controlled amplifier circuit and sampling circuit. Voltage measurement circuit includes PT isolated signal acquisition circuit, program controlled amplifier circuit and sampling circuit. By 16 bit single chip microcomputer using computer digital real-time acquisition method, by measuring the voltage signal amplitude, according to the voltage proportional relationship, high pressure can be calculated measured voltage value, by measuring the voltage signal amplitude and setting value compared to realize the function of automatic timing, according to the current proportion relations, can calculate the current output size, by measuring the current/voltage signal amplitude comparing with set point to realize the function of over-current protection.
