The four main reasons for transformer burnout are

 1.Overload: When a transformer is subjected to a load that exceeds its rated capacity, it can overheat and eventually burn out. Overload can be caused by excessive load, grid faults, or short circuits.

  2.Short circuit: A short circuit occurs when there is a direct low impedance connection between the windings of a transformer or between a winding and ground. A short circuit can result in a large current flowing through the transformer, causing overheating and eventual burnout.

  3.Insulation damage: The insulation material in a transformer serves to isolate the current. If the insulation material becomes aged, damp, heated, or mechanically damaged, the insulation performance can deteriorate, allowing current to bypass the insulation and causing short circuits or overheating, leading to burnout.

  4.Poor cooling: Transformers require a cooling system to dissipate heat and maintain normal operating temperatures. If the cooling system fails, the cooling medium is insufficient, or the cooling fins are blocked, the transformer may not be able to effectively dissipate heat, resulting in overheating and burnout.

LuShan, est. 1975,  is a Chinese professional manufacturer specializing in power transformers and reactors for 48 years. Leading products are single-phase transformer, three-phase transformers, DC inductors, AC reactors, filtering reactor, expoxy resin high-voltage transformer and intermediate, high-frequency products. Our transformers and reactors are widely used in 10 application areas: rapid transit, construction machinery, renewable energy, intelligent manufacturing, medical equipment, coal mine explosion prevention , excitation system, vacuum sintering, central air conditioning.
