Question
**Title: Understanding Power Factor and Efficiency in Induction Motors** **Introduction:** This educational module focuses on the analysis of a three-phase 1000 HP, 4160 V induction motor. This motor operates at an efficiency of 95% and a power factor of 0.85 lagging. The goal is to explore the effects of these parameters on the motor's performance when it delivers rated power to a load. **Content:** **1. Calculating Power Parameters:** *a) Calculate P, Q, and IL:* - **P (Active Power):** The real power delivered to the load, measured in watts (W) or kilowatts (kW). - **Q (Reactive Power):** The power stored and released by the inductive components of the load, measured in volt-amperes reactive (VAR) or kilovar (kVAR). - **IL (Line Current):** The current flowing through the power line to the motor. **2. Adding a Capacitor Bank:** *b) A 300 kVAR capacitor bank is added in parallel with the motor, calculate the new line current:* - The addition of the capacitor bank improves the power factor, reducing the reactive power demand on the supply system and thus affecting the line current. **3. Power Factor Reduction:** *c) Draw the power triangle to demonstrate the power factor reduction:* - The power triangle visually represents the relationship between active power (P), reactive power (Q), and apparent power (S). By incorporating a capacitor bank, the triangle changes, showcasing reduced reactive power. **Notes:** - Rated motor power is 1000 HP. - 1 HP = 746 watts. - Efficiency is defined as η = Pout / Pin **Conclusion:** This exploration illustrates the significance of efficiency and power factor in the performance and economic operation of induction motors. By enhancing the power factor, overall efficiency improves, leading to cost savings and reduced energy losses.
