| Abstract: | The phase shift technique is widely applied in the field of relay protection.The analogue and analysis approach to the failures can be obtained by phase shifting between signals with same frequency.Furthermore.the phase shift is also a signal source for phase calibration equipment and relay protector system.This paper describes the concept of phase shift by introducing an digital phase shift method based on single-chip.Specific analysis of the method is also included. |
