Time synchronization mode is very important for error calibrating of electronic transformer in the digital substation. This paper firstly introduces the technical principles of IEEE1588 time synchronization protocol, then it introduces the design scheme and technical features of a new calibration device of electronic transformer based on IEEE1588 time synchronization mode. Then, it compare and analysis the results of error calibration of electronic transformer using the calibration device, and compare the differences among the three time synchronization modes, including IEEE1588,B code and PPS. The test results verifies the IEEE5588 time synchronization mode has more advantages in the error calibrating of electronic transformer, and provides the references of IEEE1588 time synchronization protocol using in the smart substation.
