kVA to kW Formula:
From: | To: |
The kVA to kW conversion calculates real power (kW) from apparent power (kVA) using the power factor. This is important in electrical systems to understand the actual power being used versus the apparent power.
The calculator uses the formula:
Where:
Explanation: The power factor represents the ratio of real power to apparent power in an AC electrical system.
Details: Power factor is crucial in electrical engineering as it indicates how effectively electrical power is being converted into useful work output.
Tips: Enter kVA value (must be positive) and power factor (between 0 and 1). Typical power factors range from 0.8 to 0.95 for most industrial loads.
Q1: What's the difference between kVA and kW?
A: kVA measures apparent power (the vector sum of real and reactive power), while kW measures real power (actual work being done).
Q2: What is a good power factor?
A: Generally, a power factor of 0.95 or higher is considered good. Values below 0.85 may incur penalties from utility companies.
Q3: Can power factor be greater than 1?
A: No, power factor ranges from 0 to 1. Values above 1 would indicate measurement errors.
Q4: Why is power factor important?
A: Low power factor means higher currents are needed to deliver the same real power, increasing energy losses in distribution systems.
Q5: How can power factor be improved?
A: Power factor correction capacitors can be added to offset inductive loads and improve power factor.
