Converted current signal by mutual inductance coil is merely microampere level when using current transformers measure milliamps-power currents, the weak signal is too easily be interference by external environment to achieve accurate measurements. For the power current below 6mA, designed a system based on energy metering chip ADE7816. By analyzing the experimental results, proposed schemes to reduce the measurement error for the first time. The results show that, when the load is maintained at 10Ω and the value of PGA is set to 4 from 0, the average relative error of results is reduced to 0.63%; additionally, when the value of PGA is maintained at 0, but the load Increased to 52Ω from10Ω, the average relative error of results is 0.02%.
