The Effect of Filter Capacitors on Interference Characteristics of Three-Phase Power Supply Networks

It is normal practice to consider single-phase measurement of interference characteristics of three-phase delta systems as representative of all three phases. The validity of such procedures was investigated using the symmetrical components theory, and the relations between the distribution of electronic equipment between phases and phase voltages on the phase voltages of the capacitive load system was analyzed. A chart was presented to facilitate the determination of phase voltages of a capacitive load system from the knowledge of capacitance in the phases.
