METHOD FOR DETERMINING THE RELATIVE PHASE SHIFT OF TWO SYNCHRONOUS HARMONIC SIGNALS

摘要

The proposed method for determining the relative phase shift of two synchronous harmonic signals consists in defining the reference point (T0) for determining the phase (T1) of the signal U1 within the range of ? + T0, determining the phase (T2) of the signal U2 relative to the reference point (T0) and the shift of the phase of the signal U2 relative to the phase of the signal U1. The proposed method provides a possibility to reduce error in measuring phase shifts of signals at different values of the ratio between the amplitudes of the signals.
