2. Different sizes

Typically, power transformers are larger in size than their counterparts for distribution transformers.

Furthermore, the installation process of power transformers is very complex and challenging.

Therefore, compared to power transformers, 5MVA distribution transformers are smaller and lighter. The installation process is also simple. In particular, the 5MVA pad-mounted transformer has a compact structure and is easy to install and maintain, so it is widely welcomed by Bitcoin customers in North America.

How to choose a 5 MVA  transformer?

5mva-transformer
1. First, investigate the power supply voltage of the place where the electricity is used, the actual electricity load of the user, and the conditions of the place where it is located, and then select one by one according to the technical data indicated on the transformer nameplate;

2. Consider the primary voltage, secondary voltage, current and environmental conditions of the 5mva transformer.

3. During normal operation, the power load of the transformer should be about 75-90% of the rated capacity of the transformer. In operation, if it is measured that the actual load of the transformer is less than 50%, the small-capacity transformer should be replaced. If the rated capacity of the transformer is greater than 5MVA, the large transformer should be replaced immediately.

4. It is best to choose a low-voltage three-phase four-wire power supply. This can provide power and lighting power at the same time.

What is the function of 5 MVA transformer oil?

1) Insulation properties

Increase the insulation strength of each component in the 5MVA power transformer. The oil of the transformer has good insulation strength and fluidity. It can fill all parts and any space of the transformer, and discharge the air, avoiding contact between the parts and the air, and affecting the insulation strength. Between the windings and the tank shell to maintain good insulation.

2) Heat dissipation performance

Transformer oil cools the core and windings of the transformer. During the operation of the transformer, the temperature of the oil near the winding and the iron core rises after being heated, the volume expands, and the specific gravity decreases and rises. During the cycle, heat is dissipated to the cooling device, which cools the core and windings.

3) Anti-corrosion performance

Transformer oil can keep insulators (such as wood, etc.) the original chemical and physical properties, and make metals (such as steel, etc.) play a role in anti-corrosion.

Why transformers are used in MVA?

MVA is the capacity unit of the transformer. We will use MVA for large-capacity transformers, which is not very common. The common capacity unit of transformers is kVA, which is generally used in small and medium-sized transformers. So what is the direct relationship between MVA and kVA? They can be converted, 1000kVA=1MVA. Then the 5000kVA transformer is also called the 5MVA transformer. Therefore, high-voltage transformers and large-capacity medium voltage transformers are often represented by MVA, such as 13.8kV 10MVA transformers, and 69kV 25MVA transformers.

Read my article on the 10.5MVA-13.8/2.4kV Substation Transformer 

Why kVA is used instead of kW?

First, we need to understand the definitions of kVA and kW and the relationship between them.

The guaranteed value of the output capacity of the transformer in the rated state, we usually express in kVA. It is a physical unit, and kVA is the apparent power or capacity of the transformer, which is the maximum transformation capacity of the transformer. kW is an active power, which refers to the active power consumed by your equipment (usually power equipment), kilowatt (kW) = kilovolt-ampere (kVA) multiplied by the power factor.

Usually, engineers design transformers without knowing the power factor of the equipment you are using, engineers supply a certain amount of amperage at a specific voltage. So if you buy a transformer, you must know the capacity and voltage of the transformer, which are the most basic parameters for the transformer.

Read on: The Ultimate Guide to 2500KVA Transformer 

What is the difference between MVA and MW?

In AC circuits, there are three concepts of electrical power: active power, reactive power, and apparent power.

MW stands for active power, represented by English letters like P, which is the electrical power required to maintain the normal operation of electrical equipment, that is, the electrical power that converts electrical energy into other forms of energy (mechanical energy, light energy, thermal energy).

Kvar means reactive power, which is expressed as Q in English letters. It is used for the exchange of electric field and magnetic field in the circuit and is used to establish and maintain the electric power of the magnetic field in electrical equipment. It does not perform external work but converts it into other forms. energy. All electrical equipment with electromagnetic coils will consume reactive power to establish a magnetic field. Reactive power is by no means useless power, it is very useful. The motor needs to establish and maintain a rotating magnetic field to make the rotor rotate, thereby driving the mechanical movement. The rotor magnetic field of the motor is established by obtaining reactive power from the power supply. The transformer also needs reactive power to generate a magnetic field in the primary coil of the transformer and induce a voltage in the secondary coil. Therefore, without reactive power, the motor will not rotate, the transformer will not be able to change the voltage, and the AC contactor will not pull in. Under normal circumstances, electrical equipment not only needs to obtain active power from the power source but also needs to obtain reactive power from the power source. If the reactive power in the power grid is in short supply, the electrical equipment will not have enough reactive power to establish a normal electromagnetic field, then this electrical equipment cannot be maintained at rated conditions, and the terminal voltage of the electrical equipment will drop. Thus affecting the normal operation of electrical equipment.

MVA stands for apparent power, which includes reactive power and active power, and is represented by the English letter S. Apparent power is the product of voltage and current. In a three-phase AC circuit, it is the product of three times the root sign of line voltage and line current. Its size is related to the power factor. In the AC circuit, we call the product of the RMS voltage and the RMS current in the sinusoidal AC circuit the apparent power, that is, S=UI apparent power does not represent the actual power consumed by the AC circuit, but only the maximum power that the circuit may provide. or the maximum active power the circuit may consume. Apparent power reflects the total capacity of the system because there are both resistive active power and inductive reactive power in the power distribution system, which is why the apparent power is greater than the average power. Only then the network or device can work properly. Therefore, the apparent power reflects the maximum total capacity of the system. The power factor cosφ reflects the system's active power utilization level.

Only when there is only a resistive load in the power distribution system, the active power is equal to the sub-apparent power, otherwise, the apparent power is always greater than the active power, that is, the apparent power is not the actual power consumed by the resistive load. For the sake of distinction, the apparent power is not in watts (W), but in volt-amperes (V·A). Power transformers often use MVA as the unit of capacity. The reason is that when the load is not determined, the size of active power (symbol P, unit W) and reactive power (symbol Q, unit VAR) cannot be obtained. Only use MVA as The unit represents the apparent power, the symbol S, so the capacity of the transformer, called the apparent power, includes all the output of active and reactive power.

Conversion of MW and MVA

Active power P, reactive power Q, apparent power S, the relationship between them is represented by a right triangle, the hypotenuse is represented as apparent power (S), and the adjacent side of apparent power represents active power (P), the angle between them is (φ); the opposite side represents the reactive power (Q).Conversion of MW and MVA

For three-phase circuits:

S=√3 UI=√(P²+Q² )

P=√3 UIcosφ=Scosφ

Q=√3 UIsinφ=Ssinφ

How Many Kilowatt Motors Can A 5MVA Power Transformer Bring?



First, calculate the rated output current value of the secondary side of the transformer according to the formula, that is, I=5000000÷1.732÷400=7217A.

Knowing the rated current value, then take 80% of the full load, which is the current value of 5773A. Generally, a three-phase asynchronous motor has 1 kW and 2A. In theory, if all motors run at the same time, only a 5773/2=2886 kWh load can be carried.

Through the above calculation, we can conclude that a 5MVA power transformer can drive a three-phase asynchronous motor with a total power of 2886 kilowatts at the same time.

Cooling medium for 5 MVA transformer

The cooling system of the transformer is determined by the type of the transformer:

1. The dry-type transformer is cooled by external air, so its cooling medium is air.

2. The cooling medium of oil-type transformers is transformer oil, silicone oil, etc., of which transformer oil is the main body and is divided into 25# and 45# oil for insulation. Now some energy-saving and environmentally friendly transformers, especially foreign-funded transformer factories, use new insulating oils such as silicone oil and silicone oil.

3. Now some large transformers are also cooled by sulfur hexafluoride, so the cooling medium is sulfur hexafluoride.

However, prices for the most costly models might range from $78,000 to $90,000.

You should purchase your preferred brand from online shops or straight from their official website.

What Other Factors Add To The 5 MVA Transformer Price?

Generally, the 5 MVA transformer price is also influenced by several factors. 

There is a good chance that the cost of delivery will add an extra $600 to $1,000 to the overall price of the transaction. 

The proximity of the two different places to one another will be the determining factor.

In addition, the size and complexity of the instruments that are necessary to operate a 5 MVA transformer both play a factor.

Furthermore, the amount of copper wire that is generally utilized in the primary construction of the transformer is the primary factor that decides the cost of the transformer. 

When compared to aluminum wire, the cost of copper wire is significantly greater.

In transformer cores, copper is typically used since it possesses a greater resistance than aluminum does. 

Aluminum is also a common material. It's the same material used to make the windings. 

Switching to aluminum windings, which not only save money but also have lower eddy losses than copper windings, may be the best option for you.

Insulating oil components are frequently found in 5 MVA transformers.

Some examples of such add-ons include fuses, load switches, and overload relays. More equipment will likely be necessary for maintaining the appropriate temperature constant.

These include electrical rooms, air-conditioned portions of buildings, subterranean vaults, and similar sites.

Cooling Agent

A 5000kva transformer stores as much as 115 gallons of cooling fluid.

KNAN is the preferred cooling method.

Biodegradable Fluid

Instead of utilizing mineral oil, a 5000 kVA transformer is better to cool with a recyclable fluid.

When compared to mineral oil, the fire and flash points of vegetable oil are significantly greater.

Gauges

Fluid temperatures, pressures, and levels may all be highly monitored with the help of the system's display indications. 

Most liquid level and temperature measurements are still generally done using analog, hand-read gauges.

Pressure Systems

In the case of a malfunction, the 5000 kVA transformer is often equipped with a fault pressure system. 

To detect and avoid potentially harmful pressure surges, fault pressure devices are commonly fitted in the storage tanks of 5000kVA transformers.

Rapid Rise Relay

5 MVA transformer does not have any fast-acting relays for a rapid rise in voltage. 

When the pressure within the relay reaches a certain threshold, an alert will notify.

Surge Arrestors

5 MVA transformers come with built-in high surge arrestors, while others need the consumer to purchase and install the feature themselves.

Surge arrestors for high elbows are often installed in the secondary voltage of a 5 MVA transformer. These devices shield the 5 MVA transformer from all extreme weather circumstances.

Valves

There is pressure relief, fill, drain, and sample ports on the 5000kVA transformer.

What Are The Typical 5 MVA Transformer Dimensions?

In most cases, 5 MVA transformer dimensions are 108 inches. 

At the same time, its height is 84 inches followed by a width size of 96 inches.

A 5 MVA transformer weighs about 11339 kg. That is equivalent to the weight of a semi-trailer truck.

Moreover, a transformer rated at 5MVA (5000kVA) has an oil capacity of 3030 liters of 3,000 to 4,500 gallons, depending on the specific design and manufacturer. 

It's important to note that the oil capacity can vary depending on the specific transformer, so it's always best to consult the manufacturer's specifications or consult with an expert in the field.

Why Are 5 MVA Transformers Beneficial?

The primary advantage of using a 5 MVA transformer is that it provides access to more power.

The 5 MVA transformer has a transfer capacity of a maximum of 5000 kVA which is the greatest power rating it can safely handle.

It shouldn't be too difficult for a transformer rated at 5 MVA to provide electricity to a sizeable commercial or industrial structure.

It is usual practice for a 5 MVA transformer to be typically constructed using more durable materials, which increases the transformer's resistance to wear and tear.

What Are The Two Categories Of A 5 MVA Transformer? 

5 MVA transformer ratings may be usually broken down into two categories.

These are generally classified as oil-filled (liquid-type) and dry-type (solid-state).

Oil-type 5 MVA transformers contain combustible liquids, as their names imply (usually mineral oil – but can also be hydrocarbons or silicone for other liquid types). 

Dry-type 5 MVA transformers rely on their high levels of insulation to keep their internal temperatures below the ignition point, as they contain no combustible components.

Dry Type 5 MVA Transformers

To prevent overheating, the insulation of a dry-type 5 MVA transformer should be generally designed to allow for free ventilation. 

Compared to oil-filled coils of the same voltage and capacity, they are far more substantial and heavy. 

Producing dry type 5 MVA transformer versions is more expensive since they use more raw materials. 

Natural cooling systems are costly and unpredictable, thus power distribution units must run hotter to achieve optimal efficiency.

Because there is less of a risk of fire with dry-type 5 MVA transformer, it enables installation closer to the intended location. 

This occurs in all sorts of settings, from medical facilities and airports to power plants and commercial centers.

Oil type 5 MVA Transformers

Oil-type 5 MVA transformers require open air for cooling since they use combustible substances. 

It's worth noting that modern oil-filled 5 MVA transformer utilize fewer combustible liquids than in the past, so they may be generally employed in areas with stringent environmental standards.

Oil-type 5 MVA transformers have a maintenance plan that includes oil analysis, cleaning, and an examination of all moving parts. 

Technically speaking, an oil type 5 MVA transformer could be easier and cheaper to maintain and repair than a dry type one 5 MVA transformer.

Is A Dry Type 5 MVA Transformer More Expensive Than an Oil Immersed Transformer?

Yes, dry-type 5 MVA transformer costs more than oil-type 5 MVA transformer.

Since they require additional insulation, which is more expensive to build, dry-type transformers are often more expensive than oil-immersed transformers.

 Dry type 5 MVA transformer have a higher price tag since they take more time and effort to maintain. 

 Another benefit that comes with using dry type 5 MVA transformers is that they have a longer lifespan, which may sometimes assist to make up for the greater initial cost.

Oil-filled transformers are often more efficient than dry-type transformers, even though dry-type transformers are more frequent.

Because of their dry-type construction, not only are they long-lasting and reasonably priced, but they also provide dependable service.

Overall, dry type 5 MVA transformers are less attractive due to their higher energy consumption as well as their higher operational expense.
