C. A 50 hp, 440V,60 Hz, 3 phase motor operates at full load with an efficiency of 89% and a power factor of 0.85 lagging. Determine the capacitance in microfarad per phase of a wye-connected capacitor bank to be connected across the motor terminals to improve the power factor to 0.95 lagging.
INSTRUCTIONS:
I really need to understand this. Please follow and I'll give an upvote without any questions. Do not answer if you don't know, please I'm trying to study while working.
• If using calculator, please input at the solution. Example: "Just click at 'Mode 2 5" like that
• Always write the complete formula including derivation of the fomula
• When writing a formula, please input the exact word terminology. Example: Ia = Van/Zan where Ia is a phase A line current
• Always put explanation at the computation.
