| Abstract: | This paper outlines the technical principles and features of pulses per second（PPS）,Bcode and IEEE1588time synchronization protocols of three kinds of time synchronization modes,and introduces the characteristics of synchronized pulse method and fixed delay method on electronic transformer.Besides,the paper compares the error calibration methods of electronic transformer under three different means of synchronization,from which it arrives at and analyzes the error data and curve comparison chart.According to the results,the IEEE1588time synchronization method,with wider range of application,can be used in the on-site error calibration for electronic transformer. |
