RESEARCH OF PHASE STANDARD OF THE STATE PRIMARY STANDARDS OF UNIT PHASE SHIFT ANGLE BETWEEN TWO VOLTAGES
The measurement of the phase shift angle (PSA) between two voltage harmonics is important in many areas of electrical engineering and electronics. They are used in the analysis of alternating currents and electrical systems and are a key tool for evaluating their quality and efficiency. The main purpose of phase meters is to measure the phase shift, which allows analyzing the operation of electrical and electronic systems, increasing their efficiency, and diagnosing malfunctions. Phase meters directly measure the PSA between two signals.
