• June 5, 2019

An electrical transformer is a critical component in bringing electricity safely into our homes. When they fail or are damaged during a severe storm, an explosion occurs and power is cut. Electrical transformers can be very dangerous if they are not maintained or repaired properly, which is why it is important to know what to do when a transformer blows.

What Is an Electrical Transformer?

The electrical transformers located in your neighborhood are used to “transform” electrical energy. They help to transport electricity more easily and efficiently over long distances. Most important, they convert high voltage from the city’s power grid to a lower voltage that is safe to enter into homes. This is known as “stepping down” the voltage so that it is suitable for use.

What Should You Do If It Is Damaged?

Electrical transformer explosions can occur for a variety of reasons:

• Lightning strikes
• Overheating during hot summer months
• Wear, corrosion, and moisture
• Power surges
• Damage to the electrical system anywhere along the line.

When a transformer fails, the results are a loud boom, a power outage, and perhaps even some amount of fire that can create a large plume of smoke. Since the electrical transformer is a critical link to your home’s power, huge problems can result when one is no longer operating. Unfortunately, it can take a while for it to be fixed.

Anyone who is not certified should stay clear from a failed transformer and wait on the experts to arrive. Once the fault has been reported, remain indoors and use flashlights, generators, or candles until power can be restored. Depending on how severe the damages are from the outage, it may take a few hours or a few days to sort out the issues and replace the transformer.
