Reasons Behind Transformer Failure

 

Oil transformers are crucial in all electrical systems. In order to work in the best performance we need to know the reasons behind transformer failure. Different parameters can be the reason behind the failure.

The lifetime of transformer is a critical information to determine failure reasons that may be caused due to wear.The heat induced in transformer can lead to degradation of insulation with time, especially when the transformer is overloaded. 

Overloading will lead, for sure, to overheating and cracks will start to propagate through the insulation. preventive maintenance will help in the diagnosis of this problem early through measuring of moisture or dissolved gas in oil.

one of the most common failures is the line surges. This could be prevented by installing maintenance of surge protections. What is more, tightening and checking of ground connection of surge arrester is important.
