How to judge whether the temperature change of the transformer is normal or abnormal?
1. How to Judge Whether the Temperature Change of a Transformer is Normal or AbnormalDuring operation, losses in the transformer’s core and windings are converted into heat, causing temperature rise in various parts. This heat is dissipated through radiation, conduction, and other means. When heat generation and dissipation reach equilibrium, the temperature of each part stabilizes. Iron losses remain nearly constant, while copper losses vary with load.When inspecting a transformer, record
