Capacitor Bank Sizing for Power Factor Improvement

In this video, Uday Pandit explains how to size a capacitor bank for power factor improvement. The process involves four steps: calculating the total connected load, selecting the desired power factor, calculating the capacitor bank size using a specific formula, and selecting the appropriate capacitor bank size from available market options. The video concludes with a summary and a call to action for viewers to subscribe to the channel.

In Step 1, what is the total connected load calculated for the hotel building?

• 400 kilowatt

• 500 kilowatt

• 600 kilowatt

• 700 kilowatt

Which load is NOT considered in the total connected load calculation for the hotel?

Why is selecting a desired power factor important?

• It alters the building's architecture

• It changes the voltage level

• It affects the efficiency of power usage

• It determines the color of the capacitor bank

What is the formula used to calculate the capacitor bank size?

• Total load divided by tan into cos inverse of reference power factor

• Total load multiplied by tan into cos inverse of reference power factor

• Total load minus tan into cos inverse of reference power factor

• Total load plus tan into cos inverse of reference power factor

What is the calculated capacitor bank size for the given example?

• 350 kVAR

• 200 kVAR

• 300 kVAR

• 250 kVAR

In Step 4, what should be done if the exact calculated capacitor bank size is not available in the market?

• Select any available size

• Select a size based on color preference

• Select a size equal to or above the calculated value

• Select a size below the calculated value

What is the final proposed capacitor bank size to achieve the desired power factor?

• 400 kVAR

• 350 kVAR

• 300 kVAR

• 250 kVAR

What is the purpose of the automatic power factor correction panel mentioned in the video?

• To reduce the number of electrical appliances
