15 MVA TRANSFORMERS: The Ultimate FAQ Guide

What is a 15 MVA transformer, and what is it used for?

15 MVa transformers are designed to carry much higher loads than ordinary transformers and operate at high outputs, lower temperatures. MVa transformers also carry increased static and dynamic ratings, as well as a longer life expectancy.

A 15 MVa Transformer can operate at a voltage input of 1500 V. It’s most commonly used in applications that require high power and low current (not designed for residential use). You can easily find this type of transformer in arc welding machines, industrial plants, and electric robots.

Additionally, a 15 MVa transformer transfers electrical power from source to destination. The transformer has a primary and secondary winding, and you can use it for AC or DC power. This device is often found in the power distribution system of electric utility systems such as substations.

Daelim MVa transformers have specifications that are high-performance, highly efficient, and safe. They also meet ANSI, IEEE, CSA, and IEC standardization requirements. If you’re looking for a top-notch and safe 15 MVa transformer, Daelim has all the features you need!

A 15 MVA transformer is a high-capacity electrical transformer that can convert power from one voltage level to another in power systems. It is used in power generation, transmission, and distribution systems, as well as in industrial and commercial applications.

What are the typical 15 MVa transformers configuration?

Three-Phase Design

Three-phase transformers are the most common type of transformer in use today. They can deliver up to 15 MVa (megavolt amperes) of power, which is important because they have many applications.

Also, these transformers create a magnetic field that generates an electrical current from the power supply. The transformer can adjust the voltage and current by using one or all of these phases.

Additionally, the three-phase transformer is a device that uses three different voltages. It consists of three identical coils, each with a separate voltage. Then, it rotates them at the same speed against one another. The transformer’s output current varies according to the number of turns in each coil.

It is used to step up or down the voltage to transform any single voltage source into three separate phases. Then, these are connected using a common bus bar.

Thus, for a transformer to work, it must be in a three-phase configuration. The primary coil is in the middle, and the secondary coils are on either side of it. The design of three-phase transformers is more efficient than single-phase designs. This is because there are fewer resistances in this type of transformer.

Oil-Submerged Cooling

Oil-cooling is the most efficient method for power transformers to maintain their rated load. This type of cooling also can reduce operating costs by up to 40% with no additional investment.

When designing systems that require higher transformer ratings, oil-cooling is the most cost-effective way to go.

Pros

Larger transformers can be worth it because of their efficiency and high reliability. The extra money spent on oil-cooled transformers can help your company save money in the long run.

Additionally, Oil-cooling is one of the most important features of a transformer. The oil-cooled transformer can deliver up to 25% higher energy than a three-phase transformer with the same rating. This allows for increased efficiency, reduced size, and reduced cost. 

Lastly, oil-cooled transformers are more resistant to power surges and reduced susceptibility to mechanical damage.

Cons

Although sometimes the oil oxidation products in transformer oils may affect the transformer. Oil oxidations are highly harmful acids that can attack insulation and other materials, causing overheating and degrading insulation. This will ultimately result in increased operating costs due to increased maintenance.

Winding Design

15 MVa transformers are available in designs that are either two-winding or three-winding. They are usually either single-phase or three-phase power transformers. 

Single-phase, two-winding transformers are used for low-power applications. However, three winding transformers are used for medium and high power applications.

Also, the two-winding design features one winding on the bottom and a second winding on top. This design is used in many different transformers, including step-up, step-down, and three-phase designs. 

The three-winding design has separate windings for the primary and secondary voltages.

What are the different types of the core?

A transformer core is a magnetic device used to step up or step down high voltages following the Transformers, Inc. They are made of copper, iron, nickel, or aluminum. Transformers are essential in most electrical engineering applications, including the distribution of power. The output voltage is determined by its input voltage and the number of turns on its coils.

Amorphous Steel and Metals

Amorphous steel is a transformer core made up of an amorphous alloy, which means it has no crystalline structure. This type of core is used in transformers that are designed to remain stable at high temperatures. 

The amorphous steel can be magnetized or demagnetized depending on the needs of the application. Furthermore, the Amorphous Steel core creates a transformer for greater efficiency and power output. 

Carbonyl Iron

Carbonyl Iron type of transformer cores is specially designed to reduce the risk of fire and electric shock. These types of transformers contain a very high percentage of iron material, which is denser than copper.  They’re also more resistant to corrosion and will carry heavy currents for a longer time.

Ferrite Ceramics

Ferrite Ceramics are the most commonly used type of core in transformers. They tend to be less expensive than other cores, but they are more fragile and require more maintenance over time.

Moreover, ferrite ceramic has high permeability and is excellent for use in transformers. The ferrite core also helps decrease the transition losses of the transformer due to the low relative permeability. 

This type of core will help improve efficiency and decrease energy consumption. Additionally, it helps protect against wear and tear on materials.

Laminated Cores

They help prevent overheating and protect against damage caused by overvoltage, under-voltage, and general industrial accidents. Lamination provides insulation between parts of the core.

The lamination enhances the performance of the transformer by keeping its insulating properties intact. Laminating also reduces the loss of electricity that occurs when there are orientation changes.

Solid Iron

This one can carry large amounts of electricity. As the primary circuit, it runs on an alternating current (AC). The iron core takes all the power from the alternating current. Then, it transforms into a direct current (DC) with a magnetic field surrounding it.

The solid iron core can produce up to 95% less hum. Effective to keep the noise level down, which enables you to avoid hearing the protectors. Additionally, the efficiency is increased, and it helps in reducing the emission of electromagnetic radiation.

What is the MVa to kVa Conversion?

MVa is the amount of electrical energy that you can deliver through a conductor. The unit of measure is MVa. KVa is the transmission voltage at which an alternating current flows.

MVa to kVa conversion is a straightforward calculation using the formula: Kva = 2.5 * Mva. So, if you have a motor with an MVa of 15, multiply it by 2.5. The result is a Kva of 37.5.
