Assume that a three-phase distribution substation transformer has a nameplate rating of 7250 kVA and a thermal capability of 120% of the nameplate rating. If the connected load is 8816 KVA with a 0.85 lagging power factor, determine the following: (a) The kilovar rating of the shunt capacitor bank required to decrease the kilovoltampere load on the transformer to its capability level. (b) The power factor of the corrected load. (c) The kilovar rating of the shunt capacitor bank required to correct the load power factor to unity. (d) The corrected kilovoltampere load at this unity power factor.
