| Abstract: | The paper presents the design layout for the intelligent transformercalibrator, discusses the theory and the implementaion for the transformer ratioerror and angle error measurement based on the orthogonal resolutionmethod and analyses the hardware circuit main units such as input circuit, synchronousfilter, phase locked loop for phase displacement, self calibration andso on, which affect the measarement accuracy of the calibrator. At last, the paperdiscusses the anti-interference means by the software in the single chipprocessor system. |
