Calculate the supply line current, Electrical Engineering

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.
