10mva Transformer: The Ultimate FAQs Guide - Daelim
10 MVA transformer is relatively uncommon in daily life. Today I will describe it from its definition, type, specification, weight, price, etc.
What Does MVA Stand For?
MVA stands for megavolt-amperes. It is the unit of measurement for the electrical load in an engineering system. 1 MVA is equivalent to a million volt-amperes. On the other hand, 10mVA is 10,000,000 volt-amperes.
A transformer that's measured in MVA is usually a distribution transformer. The 10 MVA transformer is one of the most common distribution transformers. It is typically used to generate electricity for industrial businesses that require a strong and consistent source of power.
Without a 10 MVA transformer, these businesses would not be able to function at full capacity. Therefore, 10 MVA transformers play a crucial role in ensuring that these businesses can continue to operate smoothly and efficiently.

What is a 10 MVA Transformer?
A 10MVA transformer is a distribution transformer that can help generate electricity supply to larger industries and manufacturing plants. Volt Amperes (VA) is the measurement unit for the amount of electrical load in engineering standards.
You can also use the metric prefixes' kilo-' and 'mega-' when referring to the 10mva transformer. 1 kilo volt ampere (kVa) is equivalent to 1,000Va. Subsequently, 1 MVA is equal to 1,00,000Va. Therefore, one MVA will require 1,000kVa. So, for example, if you have a 10,000kVa demand, you will need 10mva.
Daelim understands that you need to meet the needs for a continuous power supply. We are aware of the challenges and needs our clients and customers face every day. Daelim can provide the best transformer solution for your power station, factory, and energy storage system.

What's the Difference Between MVA and Mw?
The main difference between MVA and MW is that MVA is a unit of measurement for the amount of electrical load in an engineering system, while MW is a unit of measurement for the amount of power that is being generated or consumed.
Mw stands for megawatt, and it is equivalent to one million watts. On the other hand, MVA stands for megavolt-amperes, and it is equivalent to one million volt-amperes.
Mw is usually used to measure the power output of a generator, while MVA is used to measure the electrical load of a system. 10mva transformers are typically used to generate electricity for industrial businesses that require a strong and consistent source of power.

How do you convert MW to MVA?
The equation to follow when converting megawatts (MW) to megavolt amperes (MVA) is as follows:
MVA = MW x 1,000 / Power Factor
The power factor is a value between 0 and 1 that indicates how efficiently electricity is being used. For example, if the power factor is 0.8, it means that the 10mva transformer is only using 80% of the electricity supplied to it.
When you convert 10 MW to MVA, you will get the following result:
10 MW x 1,000 / 0.8 = 12,500 MVA
This means that the 10mva transformer can handle a maximum load of 12,500 megavolt amperes.

How Many Types of 10mva Transformers Are There?
There are three types of 10mva transformers: Dry-type transformers, Liquid filled transformers, and Air cooled transformers.
Dry-type 10mva transformer is the most commonly used type of 10mva transformer. The main feature of dry type 10mva transformers is that they do not require oil for cooling, which means there is no risk of fire or explosions. Dry-type 10mva transformers are also more efficient and have a longer lifespan than their oil-filled counterparts.
Liquid-filled 10mva transformers are filled with either mineral oil or silicone oil. The advantage of using Liquid filled 10mva transformers is that they can operate at higher temperatures than dry-type 10mva transformers. However, the downside is that they are more expensive and require more maintenance.
Air-cooled 10mva transformers are cooled by Air instead of oil. The advantage of using Air cooled 10mva transformers is that they are more efficient and have a longer lifespan than dry-type transformers and liquid-filled transformers. However, the downside is that they are more expensive than both dry types 10 MVA transformers and Liquid filled 10mva transformers.
At Daelim, we offer three types of transformers with 10mva power capacity types: power transformers, small substation transformers, and pad-mounted transformers.
10 mva power transformers are machines that step up or down the voltage in long-distance power transmission lines. This is because 10 mva power transformers have a higher capacity than substation transformers.
On the other hand, 10 mva substation transformers are used specifically for substations, which are the location where the voltage is transformed from high to low or vice versa. Therefore, 10mva substation transformers are mostly used by businesses and industries since they have a higher voltage capacity.
For pad-mounted transformers, the maximum capacity is usually 5000 kVA, while the capacity of Daelim's pad-mounted transformers can reach 7.5MVA and 10 MVA.
