Power in Three-Phase AC Circuits using Phase Current Calculator

Calculate Real Power







Formula

The formula to calculate the Real Power is:

\[ P = 3 \cdot V_{ph} \cdot I_{ph} \cdot \cos(\Phi) \]

Where:

Definition

Real Power is the average power in watts delivered to a load. It is the only useful power and is the actual power dissipated by the load.

Example Calculation

Let's assume the following values:

Using the formula:

\[ P = 3 \cdot 240 \cdot 0.4 \cdot \cos(0.5235987755982) \]

Evaluating:

\[ P = 249.415316289918 \text{ W} \]

The Real Power is 249.415316289918 W.
