The PQ_sensor_3ph component is a 3-phase power quality sensor yielding the outputs real power (P_real), reactive power (Q_reactive), phase angle φ between voltage and current (phi) and power factor (cos_phi) for each phase. To this end, the voltage drops between plug plug_p and plug plug_n_voltage as well as the currents flowing from plug plug_p to plug plug_n_current are measured.
