An industrial machinery setup has 120 kW of real power capacity and operates at a PF of 0.75. Determine the total apparent power in kVA, and discuss the implications of having this PF in terms of efficiency.
💡 Hint: Use the rearranged formula for PF and critically think about its implications.
How would installing a capacitor bank with a reactive power of -40 kVAR affect the power factor of a system with an initial PF of 0.6, if the real power remains unchanged?
💡 Hint: Keep in mind the role of added capacitive reactive power in adjusting PF.
