What is Transformers?

The first transformer was made back in 1885 by Ottó Bláthy but it was later on modified by William Stanley in the same year.

And not long after that, the following year, it was commercially used in the United States of America in 1886 with the design invented by William Stanley.

Transformers regulate the electricity of buildings to prevent electrical disruptions for security.

It can be both used to increase and decrease the voltage at the power generating station. This is to mitigate the transmission losses during the transmission.

The increase in voltage is called step up while the decrease in voltage is called step down. With both purposes to supply power to the building.

In other forms of application that consist of different voltages, transformers are of great help because they can adjust the voltage to a compatible level for the appliance to work.

An example of this is that when a specific appliance requires a specific amount of voltage, and when the voltage is not at the right level, it will simply not operate. With the use of a transformer, adjusting the voltage can be easily done. Resulting in a fully functional appliance with the right amount of voltage.

For normal use, a transformer is used to increase the voltage at the power generating station, also known as the step-up transformer. This is to minimize the transmission losses during the transmission of power.

In terms of decreasing the voltage in the distribution level, this is called step-down. The purpose of this is to supply power to the building.

Moreover, there are different appliances that are manufactured with different voltage requirements. In order for the appliance to operate, you need to adjust the voltage to a compatible level.

We can achieve that with the use of a Three Phase Dry Type Transformer. For instance, specific appliances require specific voltages to run, and Transformers are used to adjust voltages to that specific requirement.

What’s the Difference between Oil Type Transformers and Dry Type Transformers?

Now that oil type transformers are often mentioned, the question that is probably on your mind is: what is it?

There are two types of transformers commonly used in industries which are either oil type transformers or dry type transformers.

Each transformer has its pros and cons, and you will get to know of each thoroughly.

The main difference of both is that dry type distribution transformers have a natural cooling medium which is air.

On the other hand, oil type uses oil and other insulating liquids.

It is important to keep this in mind if you are looking for a transformer with good longevity: Oil filled transformers have a higher energy efficiency which results in higher lifespan than dry type transformers.

Oil type transformers back then were widely used, but when dry type transformers were invented, consumers were starting to shift to it.

But why?

Each transformer has its pros and cons and it serves different aspects as well.

Depending on your personal preference, below are the advantages and disadvantages of both transformers.

The Cooling Medium

The Dry type uses natural air or forced air to cool the core and internal windings.

Whereas, the oil type transformer is dependent on mineral oil for cooling.

Disadvantage of using Mineral Oil

Mineral oil exposed to public areas is dangerous since it is highly flammable.

It has been reported that almost 70%-80% of all transformer failures are due to internal winding failures which result in fire or explosion.

It is perfectly safe for the public since its cooling medium is only air.

This is one of the main reasons why consumers choose dry-type transformers over oil-typed transformers.

Maintenance

The dry-type transformer only requires little to almost no maintenance at all. There is no special maintenance needed for its condition to stay pristine. Compared to the oil-type transformer, it does require maintenance and it should be on a regular basis.

Sample oil is regularly taken on at intervals to see whether or not it is contaminated.

Furthermore, once the breather is installed in the transformer, it will require a replacement after a certain amount of time.

Noise

The Dry Type Distribution Transformer has more noise than oil type transformers. The noise occurs because of Magnetostriction, due to this, the laminated cores are contracted or disturbed everytime air comes in contact with the magnetic field.

All the steel sheets vibrate which makes the noise. Also, there is also noise coming from the windings and load noise.

Therefore, the noise is more prominent on dry type transformers than of the oil type ones.

Dry Type Distribution Transformer

Dry Type Transformer Advantages

Dry-type transformers do well in high moisture areas because of their build design.

They are very easy to maintain as well compared to oil-type transformers.

A lot of consumers are also considering it because of its environmentally-friendly characteristic which is its less-flammable build.

Here are other benefits from dry-type transformers:

Low Cost Installation

DAELIM offers low-cost installation to their dry-type distribution transformers for your convenience.

It is known that installation costs for oil-type transformers can be more expensive but you can contact DAELIM for a better offer.

Durable

There is without a doubt that dry-type distributions transformers are durable.

In fact, they are very adaptable to certain environments that oil-type transformers cannot withstand.

Environmentally Friendly

They are less flammable, and they do not contain any oil.

This advantage right here is already a purchasing consideration because mineral oil can be expensive.

Low Maintenance

There is absolutely little to no maintenance for dry-type distribution transformers because of the mechanical properties that make them almost independent of care.

Low Fire Hazard

The oil in oil-type transformers is highly flammable.

Whereas, in dry-type distribution transformers there is oil involved.

Dry Type Distribution Transformer Advantages

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus leo.

Only Needs Air to Cool

So what does this have to do with being a disadvantage? Well, this makes liquid testing unneeded.

You will need technical personnel to clean and regularly check up on it.

Or you can do it yourself but you need to learn it first.

Electric Breakdowns

When it comes to the transformer’s windings, there are electric breakdowns between the turns or parts of the windings which is a major issue because chances are, this leads to partial discharges before an electric breakdown.

Noisy

Yes, dry-type distribution transformers are known to be louder than oil-type transformers.

This is because of the air disturbing the sheets of metal within the transformer, which makes a metal-banging sound.

What is advantage of oil in transformer?

Oil-type transformers do have a higher standard energy efficiency which gives them longer longevity than Three Phase Dry Type Transformers.

Oil transformers are also known to be less noisy compared to the metal-clanking noise from dry-type transformers its steel components produce.

However, since oil is required for its cooling, oil-type transformers will cost you more since mineral oil can be expensive, depending on where you purchase it.

Not only that, its maintenance is high as well.

There is a lot you should regularly check and clean on oil-type transformers compared to dry-type ones.
