A data acquisition system for hybrid optical current transformer was designed. The hardware circuit was designed based on 16 bit micro power consumption and high-speed chip ADS8325 and EPM240Z chip as controller. The flowchart and simulation waveforms of A/D control programs were given and the test results were analyzed. The test precision meets the IEC0.2 standards. This system features with low power consumption, excellent performance and good electric isolation.
