Sensors for current and voltage three-phase systems checking

The paper refers to current and voltage sensors relying on the orthogonal magnetization phenomenon, with which their output signals with a special pulse shape, can offer the possibility to measure in the same time, the sinusoidal sizes, like currents and voltages, and the phase difference among them. With three current and voltage sensors connected to a double spot oscilloscope, it can supervise a three-phase system, by visualization in the same time the current and voltage values and the phase difference between these sizes.
