相位误差在±10′之间

达到了0.2S级准确度的要求。

Abstract

The principle of the all fiber-optical current transducer（AFOCT） is introduced.According to IEC 60044-8:2002 standards

a calibration system is developed to calibrate the accuracy of AFOCT.Experimental results are as follows: At room temperature

the measurements of the ratio errors and the phase errors for 1% to 120% of the input rated current meet the requirements.The ratio errors and the phase errors for the input rated current are less than ±0.2% and ±10′

respectively

within-40～+80 ℃.The accuracy of prototype meets the accuracy requirement of 0.2S class.
