摘要

"Phase Angle Measurement Between Low Voltage Voltage and Three Phase High Voltage Currents, Synchronized by Radio Frequency Signal", the present invention describes as phase angle measurement between low voltage voltage and currents -phase, three-phase, radio frequency-signal synchronized circuitry that provides phase angle measurement via a low voltage remote assembly and three high voltage sensors (1), two high voltage current measuring circuits (4 ) and low voltage voltage (5), two remote synchronization circuits (6) and three sensors (7), a conditioner circuit and a lag angle squaring algorithm to enable measure electrical energy by accurately measuring angle f as the difference in angle between current and line voltage by measuring the phasors (magnitude and phase angle) of the three currents s of high voltage and a phasor of low voltage voltage, synchronously so that the phases have the same time frame.
