Transformers are an essential component of electrical systems, and they play a crucial role in stepping up or stepping down the voltage levels as required. However, sometimes transformers can overheat, leading to potential damage to the equipment and the system.
The response of the capacitive voltage transformer to the surge voltage is analyzed under the condition of lightning intruding wave and long line closing.
Transformers will come with a temperature rating in which they should be used or located. Failure to follow this can result in a transformer producing excess heat which could lead to damaged internal components. Another environmental factor that can affect the amount of heat generated by a transformer is water and dust ingress.
Transformers can get heated due to a variety of reasons. Excessive heating of the transformer increases transformer losses, weakens the insulation and may result in reduced transformer life. The principal reasons for transformer overheating are Excessive loading can cause overheating. Transformers are rated in kVA.
Generally (!) it comes down to the specification of the capacitor. If you replace a poor spec one with another, then the same failure will happen. what circuit are you trying to improve? In general, a common reason for electrolytic failure is overheating; overheating is caused by excessive current.
High temperatures can cause the insulation of the transformer to degrade, reducing the transformer’s efficiency and causing it to fail prematurely. On the other hand, low temperatures can also cause the transformer’s oil to thicken, making it more difficult for the transformer to function efficiently.
