Power Triangle Calculator - Free Online Tool

Our Power Triangle Calculator simplifies the complex relationship between voltage (V), current (I), and apparent power (S). You simply input two of these values, and the tool instantly calculates the missing third component using established electrical formulas. For example, if you know the voltage supplied to a motor is 230V and the current drawn is 10A, the calculator determines the total apparent power (S) as 2300 VA.

The tool utilizes the fundamental equation: Power (P) = Voltage (V) x Current (I). By isolating these variables, we provide accurate results whether you are determining real power (kW), reactive power (kVAR), or apparent power (kVA). No prior electrical engineering knowledge is required; just input your measurements and see the full picture of your system's load.

To get the most accurate results from the Power Triangle Calculator, always gather data from reliable sources. If possible, measure voltage and current directly at the point of connection rather than relying solely on nameplate ratings.

• Check Nameplates: Use the listed voltages and maximum operating currents from your equipment's rating plate.
• Measure Line Voltage (V): Always confirm the actual line voltage using a multimeter, as fluctuations can affect calculations.
• Consider Peak Load: When calculating for commercial setups, do not use only the average load; estimate the peak concurrent usage to size the circuit correctly.

For optimal results, try running the calculation with different potential loads (e.g., lighting vs. motors) to understand how varying components affect your overall power factor.
