What Is This Tool?
This converter allows you to change power measurements from kilovolt ampere (kV*A), a unit of apparent power in AC electrical systems, into terajoule per second (TJ/s), a unit representing very large power flows, commonly used in national and regional energy planning.
How to Use This Tool?
-
Enter the power value in kilovolt ampere (kV*A).
-
Select kilovolt ampere as the input unit and terajoule per second (TJ/s) as the output unit.
-
Click the convert button to see the equivalent power in terajoule per second.
-
Use the results to analyze or compare large-scale power system capacities.
Key Features
-
Converts apparent power units (kV*A) to extremely large-scale power units (TJ/s).
-
User-friendly interface designed for power engineers and energy planners.
-
Ideal for translating electrical load capacities into grid-level power flow units.
-
Supports high-level energy production and distribution modeling.
Examples
-
1,000,000 kilovolt amperes [kV*A] equals 0.001 terajoule per second [TJ/s].
-
500,000 kilovolt amperes [kV*A] equals 0.0005 terajoule per second [TJ/s].
Common Use Cases
-
Rating transformers, generators, and UPS systems for apparent power capacity.
-
Specifying capacity for electrical distribution equipment in buildings and data centers.
-
Estimating total power load including reactive components in industrial system design.
-
Comparing combined output of many power plants at a regional or national scale.
-
Conducting high-level national or global energy supply and demand modeling.
Tips & Best Practices
-
Remember that kV*A measures apparent power, which includes both real and reactive components.
-
Use this tool primarily for large power values, as the conversion uses a factor of 1e-9.
-
Consider power factor separately since it affects the difference between apparent and actual power.
-
Use the terajoule per second unit for high-level planning rather than detailed electrical calculations.
Limitations
-
The kilovolt ampere unit accounts for reactive power, while terajoule per second measures actual energy transfer rate, so the conversion does not account for phase angle or power factor.
-
Practical for converting only very large power measurements given the scale difference (factor of 1e-9).
Frequently Asked Questions
-
What does a kilovolt ampere measure?
-
Kilovolt ampere (kV*A) measures apparent power in AC systems, representing the product of RMS voltage and current without considering phase angle.
-
What is a terajoule per second?
-
A terajoule per second (TJ/s) is a unit of power equal to the energy transfer rate of one terajoule (10^12 joules) per second, equivalent to one terawatt.
-
Why use this conversion?
-
This conversion helps translate electrical apparent power values into very large-scale power units useful for national grid management and energy planning.
Key Terminology
-
kilovolt ampere [kV*A]
-
A unit of apparent power in AC systems equal to 1,000 volt-amperes, representing RMS voltage times current without phase angle consideration.
-
terajoule per second [TJ/s]
-
A power unit representing the transfer of one terajoule of energy per second, equivalent to one terawatt (10^12 watts).
-
Apparent power
-
The combination of real power and reactive power in AC electrical systems, quantifying total power flow without accounting for phase difference.
