-
Distinguishing apparent power from real and reactive power in AC circuits
Tips & Best Practices
-
Understand the difference between real power (kJ/s) and apparent power (VA) for accurate analysis
-
Use this conversion when power factor influences AC system measurements
-
Apply the tool for electrical equipment sizing and proper rating assessments
Limitations
-
Volt ampere reflects apparent power regardless of power factor, so direct conversion assumes ideal or known load conditions
-
Actual VA values may vary with load phase angle and power factor in AC circuits
-
Interpret converted results carefully when precise power factor data is unavailable
Frequently Asked Questions
-
What does kilojoule per second (kJ/s) measure?
-
Kilojoule per second measures the rate of energy transfer equal to 1,000 joules per second and is equivalent to a kilowatt.
-
What is volt ampere (VA) used for?
-
Volt ampere is a unit of apparent power in AC circuits, representing the product of RMS voltage and current regardless of phase differences.
-
Why might VA values differ from watts when converting?
-
Because volt ampere measures apparent power, the values differ from real power measured in watts unless the power factor is exactly one.
Key Terminology
-
Kilojoule per second (kJ/s)
-
A unit of power measuring energy transfer at 1,000 joules per second, equal to one kilowatt.
-
Volt ampere (V*A)
-
The unit of apparent power in AC circuits, calculated as RMS voltage times RMS current regardless of phase angle.
-
Apparent power
-
The product of voltage and current in an AC system, representing total delivered power without phase angle consideration.
