Explanation:
The tapping in power transformers is located in the middle portion of the winding to reduce the mechanical forces affecting the winding during short circuits. This is the correct answer because the placement of the tapping in the middle portion of the winding helps to minimize the impact of short circuits on the transformer.
Reasoning:
During short circuits, a large amount of current flows through the winding of a transformer. This current creates a strong magnetic field that can generate significant mechanical forces. These forces can lead to mechanical stress and deformation of the winding, potentially causing damage to the transformer.
Benefits of Tapping in the Middle Portion:
1. Reduction of Mechanical Forces: By placing the tapping in the middle portion of the winding, the mechanical forces generated during short circuits are distributed more evenly. This reduces the concentration of forces in any specific section of the winding, decreasing the risk of mechanical stress and damage.
2. Increased Structural Integrity: The middle portion of the winding is generally more structurally robust compared to the ends. By tapping into this section, the winding can better withstand the mechanical forces exerted during short circuits.
3. Improved Transformer Reliability: By reducing the mechanical stresses on the winding, the risk of winding failure or insulation breakdown is minimized. This helps to increase the overall reliability and operational lifespan of the transformer.
Other Options:
- Option A: Increasing the breakdown strength of the winding insulation is not directly related to the tapping location in the middle portion of the winding.
- Option B: Better cooling of the windings can be achieved through appropriate cooling systems and design considerations, and is not directly influenced by the tapping location.
- Option C: The tapping location does not affect the distribution of inter-turn voltage. The distribution of voltage across the winding is primarily determined by the transformer design and voltage regulation mechanisms.
In conclusion, the tapping in the middle portion of the winding of large power transformers is done to reduce the mechanical forces affecting the winding during short circuits. This helps to improve the transformer's reliability and minimize the risk of damage or failure.
