###### Question:

4. Sarawak Energy Berhad provides real and reactive power to a shoe's factory in the form of apparent power. Initially the shoe's factory has an uncorrected 460 kVA/month demand, 480 V, three-phase at 0.87 power factor. The billing is RM 4.75/kVA demand. However, the shoe's factory plans to install capacitance bank to raise the power factor to 0.97 in order to reduce the amount of electric bill. Table 1 is multipliers to determine capacitor (kVar) required for power factor correction. Compute: a. the capacitive reactive power required to raise the power factor from 0.87 to 0.97 by using Table 1 (2 marks) b. the actual real power consumed by the factory after the power factor correction (2 marks) c. the apparent power consumed by the factory after the power factor correction (2 marks)
