Here are a Few Reasons Why Transformers Explode Sometimes
In a power grid the voltage that flows through any point is controlled by an electrical apparatus known as transformer. For residential and commercial use these transformers control the level of voltage flowing through power lines and brings it to a level that is suitable. Now sometimes what happens is that these transformers explode or start burning all of a sudden. There could be multiple reasons of why this happens but we will focus on a few key reasons why transformers explode. There are also ways by which you can reduce the risk of these transformers burning or exploding. Any electronic components or parts required can be purchased from an electronic components store which you can easily look up online.
Causes of a Transformer Explosion
There are many reasons why a transformer can explode. Here are the three main reasons.
- If the failure is electrically induced then this can be caused by insulation failure, excess voltage, charging partially or electrification that is static.
- The failure can also be mechanically induced which can be caused by conductor tipping.
- The explosion can also be thermally induced due to reasons like when the cooling system fails, excess voltage, or over frequency.
A transformer can come up short for an assortment of reasons, yet the most well-known causes incorporate lightning strikes, over-burdening, wear and erosion, power floods and dampness. Despite the reason, the outcome can be amazing. In order to keep the transformer cool they consist of mineral oil. At the point when it becomes cheated, the wiring can make heat and a sparkle. This gigantic overpressure may ultimately make the transformer crack with a boisterous blast, streak and perhaps a fireball that can make an enormous tuft of smoke that can be seen from a significant distance. If any components are damaged you can purchase them from an electronic components store online.
Lack of Regulations and Standards
The pressure tolerance of transformers is not high and they can only withstand upto a certain limit as declared by the ASME codes and controls. These apparatuses have proven to be highly dangerous over the course of usage. The main reason of this is the lack of international transformer standards and regulations. These transformer standards to some extent describe the electrical requirements of the transformers but they do not define how they should be mechanically designed so that these risks of explosion and power surges can be reduced to some extent or eliminated.
What to do when Transformer Explodes?
As previously described there are many reasons why transformers explode therefore there are many methods by which you can reduce the probability of explosion. If the insulating fluid has a high flash point that is used in transformers the risk of explosion is reduced. The internal temperatures can be limited by the use of breakers or fuses that clear faults. In building when network class transformers are used that have thick steel, then they can withstand high pressure. This can also be reduced by reducing the access to oxygen by using a blanket of nitrogen on top of the oil limits the can hugely prevent any explosions. You can also call an expert in your area to help fix the problem and purchase any components needed from an electronic components supply store online.
