Measurement of phase/phase-to-phase voltage & line current using single voltmeter and ammeter

Overview In most of the industrial applications, electricity is distributed in three phases i.e. R-Y-B (L1-L2-L3) system. Heavy industrial loads like motors, air compressors, work on three phase supply; Thus, electrical control panels are installed for controlling and monitoring of the electrical parameters of the system. In these panels, analog meters are generally deployed for …
