In this paper,on-line capacitence measurement circuit applying potential isolated is introduced.This circuit consists of conversion of capacity to voltage,voltage amplified,mean detector,A/D conversion and digital display.Through Multisim emulation,the circuit design achieves good results.In measurement limits,the error is not more than 2%,thus able to satisfy requirement in practice.
