phase measurements

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.

AUTOMATION OF MEASUREMENTS ON THE STATE STANDARD OF THE UNIT OF PHASE SHIFT ANGLE BETWEEN TWO VOLTAGES

The phase is one of the main parameters of the oscillatory process in electric circuits and contains two components
– constant and variable. More often, it is not the actual phase that is measured, but the phase shift angle (PSA) between two
oscillating processes (voltages or currents) of the same frequency in the range from 0 to 360˚. Then the PSA is equal to the difference
between the constant components of the phases of the two oscillations and does not depend on the start of the time count.
