The formula to calculate the Real Power is:
\[ P = 3 \cdot V_{ph} \cdot I_{ph} \cdot \cos(\Phi) \]
Where:
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.
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.
