Question-2 Can you throw the emergency solution? I would appreciate it if you write legibly.
An industrial plant has a real power demand of 650 kW at a power factor of 0.65 lagging. The power is supplied by a 3-phase line at voltage of 4.16 kV (line to line voltage). You were just hired and your first task is to find the size of capacitors (in μF) required to improve the power factor to 0.95 lagging. The capacitors will be connected in grounded Y. Find- a) Calculations of the apparent power and the reactive power before the connection of the capacitors, b) Calculations of the reactive power, reactance, and capacitance of a capacitor bank required to improve the power factor to 0.95 lagging c) Calculations of the apparent power and the reactive power after the connection of the capacitors. d) Drawing of the power triangle.
