Shunt-field Excitation of a Six-pole Generator
The shunt-field excitation of a six-pole generator is crucial in maintaining the rated voltage at both no-load and full-load conditions. Here is a detailed explanation of the shunt-field excitation required for a six-pole generator:
Rated Voltage at No Load
- At no load, the generator requires 5.5 A shunt-field excitation to achieve the rated voltage.
- This excitation is necessary to establish the magnetic field in the generator's stator windings, which is essential for generating voltage.
- With 750 shunt-field turns per pole, the 5.5 A excitation ensures the rated voltage is reached when there is no load on the generator.
Rated Voltage at Rated Load
- At rated load of 250 A, the generator needs 8.0 A shunt-field excitation to maintain the rated voltage.
- The increase in excitation current from 5.5 A to 8.0 A compensates for the additional load on the generator, ensuring the voltage remains at the desired level.
- This adjustment is necessary to counteract the effects of increased armature reaction and voltage drops that occur under load conditions.
In conclusion, the shunt-field excitation of a six-pole generator plays a critical role in regulating voltage output at different operating conditions. By adjusting the excitation current based on the load, the generator can consistently deliver the rated voltage required for various applications.
