What risk is associated with overloaded transformers?

Overloaded transformers present both an increased risk of electrical fires and the possibility of transformer failure. When a transformer is subjected to loads that exceed its rated capacity, it generates excess heat as it struggles to manage the demand for electricity. This excessive heat can compromise the insulation materials and other components within the transformer, leading to an increased likelihood of failure. Furthermore, if the internal temperature exceeds safe operating limits, it can ignite surrounding materials, creating a serious fire hazard.

By understanding this, it becomes clear that the risks of electrical fires and transformer failures are interconnected. Both scenarios are the result of the transformer being overloaded, supporting the choice that both increase risks are associated with overloaded transformers.
