What type of fuse is used to protect transformers?

• A. A FUSE
• B. B FUSE
• C. C FUSE
• D. D FUSE

Answer: (A)

Transformers are typically protected by a specific type of fuse that can handle the characteristics of electrical loads they encounter. The correct answer indicates that the standard A fuse is commonly used for this application. A fuses are designed to provide overcurrent protection for transformers by interrupting the electrical flow in case of a fault, whether due to overloads or short circuits. The distinguishing feature of an A fuse is its fast-acting response, which is critical for protecting sensitive transformer windings from severe damage caused by excessive current. They are also rated adequately to ensure that normal operating conditions do not cause nuisance blowing, allowing transformers to operate effectively under typical conditions. In the context of transformer protection, it is important to have a fuse that not only interrupts current when necessary but also responds appropriately to the unique electrical characteristics of transformers, ensuring longevity and reliability of the equipment.
