The formula to calculate Power Factor (PF) from Real Power (kW) and Apparent Power (kVA) is:
\[ PF = \frac{P (\text{kW})}{S (\text{kVA})} \]
Where:
Power Factor (PF) is a measure of how effectively electrical power is being used. A high power factor indicates efficient utilization of electrical power, while a low power factor indicates poor utilization. It is the ratio of real power (kW) to apparent power (kVA).
Let's assume the following values:
Using the formula:
\[ PF = \frac{50}{62.5} \]
\[ PF = 0.80 \]
The Power Factor is 0.80.
| Real Power (kW) | Apparent Power (kVA) | Power Factor |
|---|---|---|
| 10 | 12.50 | 0.80 |
| 20 | 25.00 | 0.80 |
| 30 | 37.50 | 0.80 |
| 40 | 50.00 | 0.80 |
| 50 | 62.50 | 0.80 |
| 60 | 75.00 | 0.80 |
| 70 | 87.50 | 0.80 |
| 80 | 100.00 | 0.80 |
| 90 | 112.50 | 0.80 |
| 100 | 125.00 | 0.80 |
