The likelihood of explosion and burning of a transformer is very rare. Transformers are prepared with utmost care and precise care is taken to ensure the safety and durability. However, we cannot say that the possibility of explosions and burning of transformers is impossible. There are many aspects or things that may lead to the sudden failure of the transformer.
The Explosion of transformers in any industry or commercial space would have many serious consequences. There would be loss of lives, destruction of the area, property loss, etc. There are many reasons that can cause a transformer explosion, which everyone should take note of.
Vajra Transpower Pvt. Ltd. is one of the leading transformer manufacturers in Hyderabad, and we manufacture and supply a wide range of transformers. In this article, we have provided the information related to the transformer explosions and burning. This article includes the information related to the causes of explosions, indications, protection tips and methods, etc.
Here are some of the major reasons for transformer explosion and burning.
Aging of Transformer
Every piece of equipment works effectively when it is maintained properly. Transformers are not an exception for this, they do need proper maintenance regularly. Natural aging and improper maintenance of transformers are some of the major reasons for explosion and burning.
Generally, a protective layer, usually silicon coating, is provided on the transformer components. This layer protects the transformer from eddy currents and provides insulation. But, due to natural aging, the layer cannot withstand for a long time. So, proper maintenance is very important when the age of a transform is more.
Oil Leakage
Oil leakage is one of the important causes for transformer explosion and burning. Oil in the transformer works as coolant. So, the main purpose of the oil is to transfer the heat generated to outside.
Regular maintenance is very important, because when the oil level falls from the standard level, hot winds will be generated. This will increase the temperature of the transformer and cause burning. Also, when the oil gets overheated, it can cause an explosion as well.
Partial Discharge
Due to the high value of the electric field, electric spark happens in the transformer in a small air bubble. This phenomenon is called partial discharge, and this will raise the temperature of the transformer beyond its limit. As a result, the burning of the transformer will happen.
So, this is also one of the reasons for transformer failures and transformer burning.
Signs that Indicates About the Burn Out of a Transformer
An experienced team is very important to understand the status of the transformer. They can easily find the faults in the transformer and can stop the disruption before it happens.
Here are some of the indications that you should take seriously.
-
Unusual rise in the temperature of the transformer indicates that the transformer has some issue, which needs immediate maintenance.
-
If you hear some spark noise from the transformer, it means there is an internal connection problem. This could also lead to failure of the transformer.
-
Leakage of oil for the transformer is also a sign of failure of the transformer.
-
Sometimes the fuse blow is also a sign of an explosion of a transformer, which cannot be neglected.
These are some of the most common and popular signs that indicate failure of transformers that could result in explosion and burning.
Things You Must Know to Protect Transform for Burn Out
Maintenance plays a key role to protect the transformer from failure and burn out. From the day when you install a transformer, the maintenance must be started. Protection devices like circuit breakers, fuses and other elements must be taken care of. A small team of skilled and experienced professionals will be required to look after the maintenance of the transformer.
Here are some of the precautions that need to be taken in order to protect the transformer from burnout.
-
Monitor the performance of the cooling system such as the fans, oil pumps, radiator, etc.
-
Regularly check the oil level and change the oil if required.
-
Use paint or other weather resistive material to protect the transformer for corrosion and aging.
-
To protect the transformer against power failure and overcurrent faults, install watchdog breakers.
-
Design the protection devices and fuses properly to protect the transformer.
These are some of the top protective methods to avoid explosion and burning of transformers.
