How Long Does It Take to Fix a Blown Transformer

November 8, 2021 0

Many people have no idea how long does it take to fix a blown transformer, and that is understandable. With all the different types of electrical equipment out there, this can be a difficult question to answer. However, if you are at your wit's end because your transformer has been on the fritz for a while now, we will help shed some light on this topic!

Why Do Transformers Blow?

Transformer failures are a frequent occurrence. There are various reasons that transformers can blow, including bad design and negligence in the installation process. In addition, transformers fail when they suffer too much electrical stress or mechanical strain during normal operation. It's not uncommon for engineers to assign an MTBF (Mean Time Between Failures) rating to manufacturing lines of transformers.

A transformer's life is finite, and it will eventually fail. The three main causes for a failure are an overload on the system, a bad design that creates excessive stress in certain spots, or improper installation/wiring. Transformers may also blow when they run out of cooling water because this can lead to localized overheating, damaging the insulation.

The life expectancy of a transformer depends on the type and quality. For instance, if it is new or high-quality, an overload may last for several hundred cycles before failing, whereas in older equipment, this could be fewer than 20 cycles. Transformers are typically rated as Class 100 at 75% capacity (CSA C22) vs. Class 200 at 50% capacity (CSA C22).

How Long Does It Take to Fix a Blown Transformer

Blown transformers can be fixed by replacing the transformer with a new one. This usually takes less than an hour to complete and will require you to shut off power from your home before beginning work on it, so you don't get shocked.

If you need a fixing blown transformer, You can hire a professional technician who specializes in transformer repair, or you can follow the steps mentioned below to get started on your repairs.

Step One

The first thing you'll want to do is turn off the circuit breaker for the blown transformer area, then cut away any wires attached to it using wire strippers or a utility knife. Once this has been done, there should only be two cables and a grounding cable going into the box below.

Step Two

Next, disconnect each of these three pieces from their connections to access everything inside without damaging any other areas that are still active within your electrical system.

Step Three

After the three pieces have been disconnected, lift them out of the way so you can remove the cover to expose its insides.

Step Four

Next, find and replace all blown fuses with new ones before plugging in your replacement transformer. Once this has been done, put everything back together by reversing the steps taken to take it apart.

Step Five

Finally, reconnect any wires that need reattaching (this will be a lot quicker now because they're already cut) as well as turning on the power for each circuit breaker from which power was previously turned off. This should only require one hour or less, depending on how many breakers are involved.

Frequently Asked Questions

How to Fix a Blown Transformer?

There are a few ways. For example, you can replace the blown transformer with another one or attach an ammeter between two wires to see if the current is flowing through them and then use that information to identify where there may be a short in your circuit board.

What Happens if a Transformer Explodes?

This can be dangerous, so you should turn off the power immediately if this happens. If there is any chance that a transformer has been damaged and needs to be replaced, do not touch it yourself but call an electrician instead.

A: Sometimes you might need a new transformer because it has been overheated and damaged from being left on too long or plugged into the wrong voltage outlet. Other times just replacing fuses can be enough of a fix for blown transformers that may not have serious damage.

How Can You Prevent a Transformer From Exploding?

This is a difficult question because it depends on the transformer and its history. However, using proper voltage outlets and checking for signs of damage like overheating can help prevent your transformer from exploding in the first place.

Conclusion

We know you are wondering how long does it take to fix a blown transformer. The answer is that it will depend on the severity of the damage and what needs replacement, but in general, most problems can be fixed within 24 hours or less!

If you have a blown transformer, be sure to call an electrician as soon as possible. The longer you wait, the worse it will get and can lead to more expensive repairs in the future.
