A balanced star-connected load is connected across a three phase 450V 50 Hz AC supply. Each load element has an impedance of 5+j12 Ω.
Calculate:
(i) The power factor of the load
(ii) The supply line current
(iii) The reactive power consumed by the load
(iv) The delta-connected capacitor values required to restore the system power factor to unity.
Requirements of equalizer connection
