Understanding Short-Shunt Configuration
In a short-shunt configuration, the shunt winding is connected in parallel with the armature winding, while the series winding is connected in series with the armature. If the series and shunt windings are mistakenly interchanged and connected to the rated voltage, the following effects occur:
Series Winding Characteristics
- The series winding is designed to carry the full load current, which is typically higher than the shunt current.
- When interchanged, the series winding is subjected to the lower shunt current, which is less than its rated capacity.
Shunt Winding Characteristics
- The shunt winding is designed for a lower current and is connected in parallel with the armature.
- When interchanged, it experiences the higher series current, which can lead to overheating if the motor runs under load.
Effects of Interchanging Windings
- Since the shunt winding is now carrying higher current than it is rated for, it might get overloaded. However, the series winding, now receiving a lower current, is not overloaded.
- Importantly, the motor may still operate because neither winding is short-circuited.
Conclusion
Thus, while the shunt winding may face the risk of overheating due to excess current, neither winding is subject to a short-circuit condition. Therefore, the correct answer is:
Option A: Neither of the windings get short-circuit.
This maintains the integrity of the motor, preventing immediate damage from a short circuit while highlighting the potential for shunt winding overload.
