The formula to calculate the Real Power using Line-to-Neutral Voltage is:
\[ P = 3 \cdot I_{ln} \cdot V_{ln} \cdot \cos(\Phi) \]
Where:
The Real Power \(P\) 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:
\[ P = 3 \cdot 1.3 \cdot 68.9 \cdot \cos(0.5235987755982) \]
Evaluating:
\[ P = 232.709686250917 \text{ W} \]
The Real Power is 232.709686250917 W.
