The formula to calculate the Series Field Copper Loss is:
\[ P_{se} = I_{se}^2 \cdot R_{se} \]
Series Field Loss is the power dissipated by the series field of a generator due to current flowing through it. Series Field Current is the current due to series field windings in a DC generator. Series Field Resistance refers to the electrical resistance of the field winding in a series-wound DC motor or generator.
Let's assume the following values:
Using the formula:
\[ P_{se} = 0.832^2 \cdot 123.5 = 85.489664 \]
| Series Field Current (Ise) | Series Field Resistance (Rse) | Series Field Loss (Pse) |
|---|---|---|
| 0.8 | 123.5 | 79.040000000000020 |
| 0.85 | 123.5 | 89.228750000000019 |
| 0.9 | 123.5 | 100.035000000000039 |
| 0.95 | 123.5 | 111.458750000000038 |
