Question
**Problem Statement:**

A three-phase 1000 HP, 4160 V induction motor operates at an efficiency of 95% and a power factor of 0.85 lagging. If the motor is delivering the rated power to a load:

a) Calculate P, Q, and I<sub>L</sub>.
b) A 300 kVAR capacitor bank is added in parallel with the motor. Calculate the new line current.
c) Draw the power triangle to demonstrate the power factor reduction.

**Notes:**
- Rated motor power is 1000 HP.
- 1 HP = 746 watts.
- Efficiency is defined as: \( \eta = \frac{P_{\text{out}}}{P_{\text{in}}} \).

**Explanation:**

This problem involves calculations of active power (P), reactive power (Q), and line current (I<sub>L</sub>) for an induction motor. The effect of adding a capacitor bank on the line current and the power factor is also considered and represented by a power triangle.
