| Abstract: | The principle of optical current transducer(OCT) based on Faraday effect Was described.To process the two opti-cal signals in the OCT current measure system,an automatic gain equalizing method achieved by the hardware circuit was presen-ted,and the phase-locked loop(PLL) was used to realize the phase synchronization.The OCT system was also tested,the results show that its accuracy meets 0.2P requirements of the GB/T 20840.8-2007 standard. |
