Transformer 2500 kVA And Its Function

There are many types of transformers, and the two most prominent ones are generator transformers and distribution transformers. The transformer 2500 kVA is a distribution transformer. Its primary function is to distribute electricity to consumers from a high-voltage system to a low-voltage network of distribution lines. When it comes to design, distribution transformers are liquid-filled or dry-type.

Oil Type vs. Dry Type Transformer 2500 kVA

2500 kVA transformers are available in oil-type units. This type of transformer can carry high voltages and distribute this to communities, neighborhoods, or commercial areas. It needs a particular cooling system to dissipate heat and work safely and efficiently in different industries.


Aside from the 2500 kVA oil-type or liquid-type transformer, there is also a dry-type transformer. In a liquid-type 2500 kVA, oil is used to cool the transformer field. In dry-type units, a unique cooling system is used to keep the transformer temperatures at optimum levels.

Oil Type 2500 kVA Transformer


Oil-type distribution transformers like the 2500 kVA require regular maintenance to ensure that it works properly. There is a considerable risk of contamination of the oil used in cooling the transformer, so regular tests are necessary.


2500 kVA oil-type transformers have higher maintenance costs as contamination tests are done regularly by trained experts using special equipment. However, these transformers have a longer lifespan thanks to their high energy efficiency.


These transformers are quieter and thus, may be installed in residential areas and communities. When it comes to recyclability, oil-type units are easier to reclaim and recycle as these have higher life spans. Oil-filled units produce minimal waste and need very minimal parts replacement and labor.


2500 kVA oil-type transformers are smaller and more efficient compared to dry-type units. Oil-cooled units require minimal demand and have a lower environmental footprint.


When it comes to efficiency, oil-cooled 2500 kVA distribution transformers can take heavier loads. This is why applications that need high voltages use oil-filled transformers. The location plays a vital role in determining which type of transformer will work best.


Oil-cooled units are standard in outdoor areas as there is a possibility of spills and leakage, which could start a fire. This type of transformer is environmentally friendly compared to dry-type units.

Dry Type 2500 kVA transformer

Dry-type transformers are standard inside buildings or near structures because these pose less risk to the environment. It does not need any regular testing and is resistant to common chemical contaminants and thus, requires very little maintenance.


Meanwhile, dry-type 2500 kVA units are more expensive to maintain and operate than oil-filled units but have shorter life spans. This type of transformer tends to be very noisy. Therefore, these are considered not installed in a neighborhood or community.


Most dry-type transformer systems with 2500 kVA are harder to recycle, and thus, broken or outdated models end up in landfills and scrapyards. Because dry-type units have moving parts like the cooling system, there is the need to deal with parts replacement and expert maintenance personnel.


These dry systems are more extensive compared to oil-type units but have limited voltage and size. This is why dry-type systems are prone to overheating in case of an overload. Companies that use dry-type systems usually have high electrical losses and are very expensive to maintain.


When it comes to other transformer features, 2500 kVA dry-type transformers are best for moderate MVA and voltage ratings, and thus, these are common in low-scale applications. Finally, dry-type units are not as flammable as oil-type systems and therefore are low fire risks.


Summary of Comparison


Whether you're a small electrical distributor or a large-scale operator, understanding the advantages of 2500 kVA oil-type and dry-type systems matters. This will ensure your company's safety and efficiency. You can guarantee safer electrical loads, less worries about breakdowns, and better customer satisfaction when you use the right type of transformer.


Transformer Maintenance


The 2500 kVA dry-type transformers require very little maintenance, whereas oil-type units need regular oil contaminant testing but are safer and more efficient.


Initial and Operating Costs


Expect higher installation and parts replacement costs with dry-type units compared to oil-filled 2500 kVA systems. However, oil-type units need regular maintenance that may also increase operating costs overall.


Environmental Noise


When it comes to noise, oil-type units are not as noisy as dry transformers as oil protects the transformer's components and prevents any friction. Dry-type units have moving parts and will eventually suffer from wear and tear. Older units will become noisier and noisier unless the parts are replaced.


Transformer Recyclability


Oil-type 2500 kVA transformers are easier to recycle and have lasting parts and components than dry-type transformers. Once dry-type systems become outdated or are no longer serviceable, the parts are thrown away as these are harder to recycle or repair. Oil-type transformers last longer and can be maintained for longer periods.


Overall Efficiency


2500 kVA oil-type units are more efficient and thus, can handle large voltages and higher electrical loads compared to dry-type transformers. These are the reasons why most industries prefer to use oil-type units rather than dry-type transformers.


Location Safety


The type of transformer you need for your business or industry will depend on your location. Companies that provide service to communities, residential areas, and small to medium-scale customers have different transformer requirements than those that serve small industries, commercial centers, and other industries.


Consulting a specialist will help you better understand the right transformer that matches your industry. Always consider safety before anything when it comes to electrical distribution and efficiency

Typical Applications for a 2500 kVA Transformer

A transformer 2500 kVA is a distribution transformer. As the name suggests, this type of transformer helps distribute electrical power safely and efficiently from a source. There are different types of transformers according to the distribution system. These are single-phase, three-phase, underground, pole-mounted, and pad-mounted transformers.


Oil-type distribution transformers are available in many sizes and different efficiencies. Clients choose 2500 kVA units according to their electrical requirements and their budgets.

  • Single Phase Transformer – single-phase units are used in distributing electricity in residential areas. This is also used in light industrial and commercial spaces.
  • Three-Phase Transformer – this unit holds electricity coming from the primary circuit going to a minor circuit. This is common in commercial and residential areas as well as light industries.
  • Pad-Mounted transformer – this system reduces primary voltage for customers housed in a large building or an apartment complex.
  • Pole Mounted Transformer – these are mounted on a service pole and are common in rural areas.

How Many Amps is a 2500 kVA Transformer?

A 2500 kVA needs 6014 A. Dry-type units can handle only minor to moderate MVA as well as a voltage which makes these handy to use in smaller electrical applications. Meanwhile, oil-type transformers are able to handle heavier electrical loads and need higher voltages.

How Much Does a 2500 kVA Transformer Weigh?

For a 2500 kVA unit with a 2.5 MVA rating, the empty weight is about 8000 kg while the total weight is up to 7500 kg.

What Is the Oil Capacity of a 2500 kVA Transformer?

A 2500 kVA system with a 2.5 MVA rating has an oil capacity of 250 liters. Oil-type transformers use high-quality, high-grade transformer oils that can handle all kinds of climate conditions.


2500 kVA transformers are efficient and are ready for use in many residential, commercial and industrial areas. 2500 kVA distribution transformers are made to last and are best for demanding environments.
