Abstract
Because there is not yet a standard for the error calibration of electronic transducer in electrical power system, and the calibrator for traditional electromagnetic transformer is not qualified to the work of calibrator for the electronic transformer, the product of electronic transducers couldn't be put into use in marketplace smoothly and quickly. There is an urgent demand to develop the error calibrator for electronic transducer and to establish the calibration system. In this paper, the device used for error calibration of electronic transducer is presented. The device is designed and developed based on DSP and FPGA technology so that it has the feature of multifunction, small size, portable and suitable used in the field. The windowed interpolation algorithm is used to compensate the effect of frequency fluctuation of the power system.关键词
