1. What is Power Factor?

The power factor of an AC electrical power system is defined as the ratio of the real power absorbed by the load to the apparent power flowing in the circuit. It indicates how effectively electrical power is being used.

2. How Does the Calculator Work?

The calculator uses the Power Factor formula:

\[ PF = \frac{\sqrt{2} \times P}{V_m \times I} \]

Where:

\( PF \) — Power Factor
\( P \) — Power Transmitted (Watt)
\( V_m \) — Maximum Voltage Overhead AC (Volt)
\( I \) — Current Overhead AC (Ampere)

Explanation: This formula calculates the power factor in a single phase two wire overhead system using the transmitted power, maximum voltage, and current values.

3. Importance of Power Factor Calculation

Details: Power factor calculation is crucial for determining the efficiency of electrical power usage, optimizing energy consumption, and reducing power losses in electrical systems.

4. Using the Calculator

Tips: Enter power transmitted in watts, maximum voltage in volts, and current in amperes. All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the ideal power factor value?
A: The ideal power factor is 1.0, which indicates that all the power is being effectively used. Values below 1.0 indicate inefficiencies in the system.

Q2: Why is power factor important in electrical systems?
A: Poor power factor results in higher energy losses, increased electricity costs, and reduced system capacity. Improving power factor can lead to significant energy savings.

Q3: How can power factor be improved?
A: Power factor can be improved by using capacitors, synchronous condensers, or other power factor correction equipment to reduce reactive power in the system.

Q4: What causes low power factor?
A: Low power factor is typically caused by inductive loads such as motors, transformers, and fluorescent lighting that consume reactive power.

Q5: Are there different types of power factor?
A: Yes, there are displacement power factor ( caused by phase shift between voltage and current) and distortion power factor (caused by harmonic distortion).
