Abstract	In smart grid, the data synchronization of electronic transformer is the key precondition and guarantee for protection device to measure and operate accurately. In engineering application, the interpolation method is frequently applied to solve the synchronization problem. However, the sampling value message jitter of electronic transformer is usually caused due to the delay of network switch, the data packets line up mechanism and uncertainty of interrupt time, further resulting in the inaccuracy of interpolation method. In this paper, the influencing mechanism of message jitter on the interpolation accuracy is first analyzed, then the error expression of linear interpolation in the presence of jitter is deduced, and the influences of message jitter on linear interpolation accuracy is calculated at different sampling rates, harmonic frequency waves and jitter amplitudes. The simulation shows that the interpolating error increases with the increase of sampling rate and jitter amplitude, while the influences are relatively small on high harmonic frequency waves. The results provide important references for electronic transformer data synchronization application in the presence of message jitter.
