Question
A small industrial shop is connected to a local utility power via a Three-phase supply of 440V line to line AC. Assume balanced system configuration, the shop has a total connected three phase load of 100KW at 0.80 power factor LAGGING.
To improve the power factor to 0.98 LAGGING , a three phase WYE connected capacitor bank will be connected in parallel to the three phase supply.
1. What is the total Reactive Power of the load prior to installation of capacitor bank (kVAR)?
2. Determine the needed THREE-PHASE KVAR rating of the capacitor bank in order to achieve the improved power factor .
