1. What is Power Factor Correction?

Power Factor Correction is a technique used to improve the power factor of AC electrical systems. It involves reducing the reactive power in the circuit to make the system more efficient and reduce energy losses.

2. How Does the Calculator Work?

The calculator uses the Power Factor Correction formula:

Where:

• \( PF_{initial} \) — Initial Power Factor (0 to 1)
• \( I_{corr} \) — Corrected Current in AC Circuit (Ampere)

Explanation: The formula uses trigonometric and hyperbolic functions to calculate the corrected power factor based on the initial power factor and the corrected current.

3. Importance of Power Factor Correction

Details: Improving power factor reduces energy losses, increases system capacity, improves voltage regulation, and can lead to significant cost savings in electrical systems.

4. Using the Calculator

Tips: Enter the initial power factor (value between 0 and 1) and the corrected current in amperes. Both values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a good power factor value?
A: A power factor close to 1 (unity) is ideal. Values below 0.95 are generally considered poor and may require correction.

Q2: Why is power factor correction important?
A: It reduces energy losses, improves system efficiency, increases capacity, and can prevent utility penalties for poor power factor.

Q3: What causes poor power factor?
A: Inductive loads such as motors, transformers, and fluorescent lighting are the main causes of poor power factor in electrical systems.

Q4: How is power factor corrected?
A: Power factor is typically corrected by adding capacitors to the system, which provide reactive power to offset the inductive reactive power.

Q5: What are the benefits of power factor correction?
A: Benefits include reduced electricity bills, increased system capacity, improved voltage stability, and reduced carbon footprint.
