Analysis of the Three Main Causes of Transformer Burnout

Transformers are a widely used piece of equipment in the electrical industry, including dry-type, oil-immersed and amorphous alloy types. The principle behind transformers is the use of electromagnetic induction to achieve their purpose. However, there are a number of factors that can lead to the failure of their normal operation. In some cases, this may result in a more serious failure, such as a burnout. Today, transformer manufacturers will be presenting a summary of three key points.

Please be aware that the transformer has been operating at maximum capacity for an extended period. Such a device is often referred to as a small horse-drawn cart. Overloading the transformer for an extended period of time will result in an increased internal temperature, which will accelerate the ageing of the insulation and reduce the lifespan of the transformer.

Please be aware that a short circuit has occurred on the secondary side. It is important to note that the short-circuit current generated when the secondary side of the transformer is short-circuited can reach several times or even dozens of times the rated current. This can result in significant damage to the transformer.

A short circuit has occurred between the turns of the transformer coil. An increase in current in the winding will damage the insulation and eventually burn the transformer. It is therefore essential that the design and production process of transformers is carried out with due care and attention to detail, with the capacity chosen and the manufacturing process itself being of the highest standard.

It should be noted that transformers are, in practice, lossy. However, the relationship between voltage and current remains consistent with the aforementioned relationship.
