What can high temperatures in distribution transformers lead to?

High temperatures in distribution transformers can lead to insulation degradation because excessive heat can break down the insulation materials used within the transformer. The insulation is critical for isolating the electrical components, and when exposed to elevated temperatures for prolonged periods, its dielectric properties may deteriorate, reducing its effectiveness. This degradation can result in increased risk of electrical faults, short circuits, and potential transformer failure. Managing the temperature within the transformer is crucial to ensure the longevity and reliability of the equipment, highlighting the importance of maintaining appropriate operating conditions.
