5-3 To Improve Power Factor of a 3 φ 4W Power System Calculate KVAR , KVAR , and KVAR values of R(L1) S(L2) T(L3) each phase. Based upon the calculated values, users can purchase required 3 φ or 1 φ capacitor at rated voltage and frequency to improve power factor.
5-5 To Improve Power Factor of a 1 φ 2W Power System Calculate KVAR value of a 1 φ 2W power system. Based upon the calculated value, users can purchase required capacitor at rated voltage and frequency to improve power factor. If value of capacitance is needed, users can obtain the value by the following equation.
