If you're considering a 15 kVA transformer for your business, this guide will answer all of your frequently asked questions.
What is a 15 kVA transformer?
A 15 KVA transformer is a type of transformer with a capacity of 15,000 volt-amperes. This means it's able to supply 1,500 watts of power with a maximum input/output voltage of 35kV. In transformer standards, a 15 kVA transformer is considered a smaller size transformer.
Since it's a transformer with a considerably smaller capacity, it's usually used for domestic or small-scale commercial applications such as powering electronic devices, small motors, or for general lighting purposes. You can also use it to supply power to a single phase of your three-phase system.
Despite its limitation, a 15kVA transformer is still a capable device that's useful for transforming voltages between high, medium, and standard levels while still allowing for the transmission of decent amounts of power. It's capable of achieving this thanks to its autotransformer design.
A 15KVA transformer has unique properties that make it an excellent choice for various applications. These properties include:
- No energy is lost in the transfer of electricity between the primary and secondary circuits.
- The transformer is highly efficient, with little heat loss.
- Transformers can be used to match the impedance of the load to the source.
- Transformers can be used to change the voltage and current relationship in a circuit.

Similar to the three-phase box transformer, this device has a power rating of 15kVA, the primary voltage can be 7.2 kV,14.4kV,24.9kv, and a secondary voltage of 240/480 V, 240/120 V. The primary coil of this transformer is connected to the high-voltage side of the transformer, while the secondary coil is connected to the low-voltage side.
A pad-mounted transformer is typically small and compact in terms of physical features. The size of this transformer can range from 18 inches to 36 inches. Additionally, the weight of this device can range from 500 pounds to 1,000 pounds.
Pad-mounted transformers are typically made out of steel or aluminum. The transformer’s enclosure is designed to protect the device from damage. For example, the enclosure can prevent the transformer from being damaged by weather conditions or vandalism.
Pad-mounted transformers are typically used in residential areas to supply electricity to homes. In addition, You can also use them for both commercial and industrial applications—albeit to a lesser extent.

15kVA Oil-immersed Transformer
As the name suggests, a 15 kVA oil-immersed transformer uses oil as a cooling and insulating medium. However, with a small capacity of only 15kVA, this type of transformer is not suitable for a high-density population. Instead, it's more prevalent for small-scale applications such as powering street lights or small businesses.
In addition, using oil as a cooling agent ensures that the transformer can operate for long periods without the risk of overheating. This is due to oil's excellent thermal conductivity, which allows it to dissipate heat quickly and efficiently.
The only downside of using an oil-immersed transformer is that it's not as environmentally friendly as other types of transformers since the oil can leak and contaminate the surrounding soil and water.
Oil-immersed transformers are quite prevalent equipment in the power grid. Oil-immersed transformers are ideal for harsh environments, good at temperature regulation, strong against shocks, and have high short-circuit tolerance. They're mostly utilized in large facilities, such as data centers, sewage treatment plants, etc. The most significant thing is that they are very inexpensive.
While oil-immersed transformers have many benefits, there are also some drawbacks. For example, transformer oil is flammable and may catch fire or explode if it comes into contact with flames. Also, leaks can occur, and the insulation materials will degrade and lose their effectiveness over time.

15kVA Overhead Single-Phase Transformer
A 15kVA transformer single-phase is a type of power transformer used in distribution lines to supply electricity to households and businesses. The transformer steps down the voltage from the high-voltage distribution line to a lower voltage that is safe for everyday use.
This type of transformer is typically used in rural areas where the primary voltages are lower than in urban areas. Additionally, 15kVA single-phase transformers are also used in some industrial applications.
15 kVA single-phase transformers are available in a variety of sizes and capacities. The most common sizes include 25kVA, 37.5kVA, 50kVA, 75kVA, 100kVA, and 167kVA.
15kVA single-phase transformers are generally considered to be very reliable. However, like all electrical equipment, they do require some maintenance. For example, the transformer's oil level must be checked regularly to ensure that it is adequate. Additionally, inspect the transformer for signs of corrosion or other damage on a regular basis.

15kVA Dry Type Transformer
A 15kVA dry-type transformer, or resin or epoxy resin transformer, is a kind of transformer that uses high-grade insulation materials. The solidification of resin eliminates the voids in the windings, so it has better heat dissipation and electrical performance than the traditional transformer.
Dry-type transformers are classified into cast resin dry-type transformers and encapsulated dry-type transformers. The cast resin dry-type transformer is filled with epoxy resin while the coil is being cast. On the other hand, the encapsulated dry-type transformer is made by pouring epoxy resin into the coil after it has been wound.
Dry-type transformers have several advantages over traditional oil-immersed transformers. For example, they are more environmentally friendly because there is no risk of oil leaks. Additionally, they are more fire-resistant and have a longer lifespan.
However, dry-type transformers also have some disadvantages. For example, they are more expensive than oil-immersed transformers and require more maintenance. Additionally, they are not as good at regulating temperature as oil-immersed transformers.
