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.
