Power Factor Formula:
| From: | To: |
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.
The calculator uses the Power Factor formula:
Where:
Explanation: The formula calculates the ratio between real power and apparent power in the electrical system.
Details: Power factor calculation is crucial for determining the efficiency of electrical power usage, reducing energy losses, and optimizing electrical system performance.
Tips: Enter power transmitted in Watts, current in Amperes, and maximum voltage in Volts. All values must be positive numbers greater than zero.
Q1: What is an ideal power factor value?
A: An ideal power factor is 1.0 (or 100%), which indicates that all the power is being used effectively with no reactive power.
Q2: Why is power factor important in electrical systems?
A: Low power factor results in higher energy losses, increased electricity costs, and reduced system capacity. Improving power factor can lead to significant energy savings.
Q3: What causes low power factor?
A: Low power factor is typically caused by inductive loads such as motors, transformers, and fluorescent lighting that require reactive power.
Q4: How can power factor be improved?
A: Power factor can be improved by adding power factor correction capacitors, using synchronous condensers, or optimizing motor loads.
Q5: What are the typical power factor values in industrial systems?
A: Industrial systems typically have power factors between 0.7 and 0.9. Values below 0.7 are considered poor and may incur penalties from utility companies.
