A 100 kVA, 230V load operates at 0.80 lagging power factor. The power factor is to be improved to 0.80 leading by a capacitor bank. However, the capacitors are loosely connected and take 50 kW when connected to a 230V, 60Hz AC source. a. What is the total KVA consumption when the capacitor bank is connected? (162.5 kVA) b. What is the kVAR rating of the capacitor bank? (157.5 kVAR) c. Find the capacitance of the capacitor. (7.8976 mF)
