An Encyclopedia of 200 kVA Transformer

A transformer is an electrical device based on the principle of electromagnetic induction, which allows electrical energy to be transferred between circuits without metal connections. It is an important part of electricity consumption, transmission, and distribution. 200 kVA transformer is a typical rated capacity in all types of transforms.

 

Dealim Electric has designed, produced, and tested all kinds of 200 kVA transformers and exports to U.S. and Canada with the CSA, ANSI/IEEE standards. 200 kVA transformers are the only rated capacity manufactured by Daelim, we can also provide other rated capacity transformers. Next, let's learn more about the 200 kVA transformer.

Types of 200 kVA transformer

Nowadays, with the continuous development of science and technology, there are more and more types of transformers. From different perspectives, transformers can also be divided into many types. From the point of view of use, it can be divided into power transformers, test transformers, measurement transformers, and special purpose transformers. From the point of view of phase number, single-phase transformers, three-phase transformers, and multi-phase transformers are included. From the point of view of transformer windings number, it can be divided into double-winding transformers and multi-winding transformers.

 

There are many types of electric transformers that are only at 200kVA level. It can be divided into 200kVA single-phase pad-mounted transformers, 200kVA dry-type transformers、200kVA, and 3PH distribution transformers.

200 kVA Single Phase Pad Mounted Transformer

The appearance of the 200 kVA single-phase pad-mounted transformer is very different from an ordinary three-phase distribution transformer. It’s constructed with coil, wing, fuses, load break switches, and current limiting fuse in a square oil tank. When you walk outdoors to see the beautiful green box (also gray) on the lawn, it is a single-phase pad mounted transformer. It is small and beautiful, usually used in residential areas.

 

Daelim's single phase pad mounted transformer, as well as 25kVA, 50kVA, 75kA, 100kVA, 167kVA, 250kVA, and another capacity. Meet or exceed standard requirements such as CSA C227.3, ANSI/IEEE, and DOE 2016. In addition, Daelim single pad transformer with UL, cUL listing.

 

There are a large number of application cases in the North American and South American markets of Daelim single phase pad mounted transformers. If you have any inquiries or questions, please contact Daelim immediately.

200kVA Dry Transformer

200kVA dry-type transformer is a transformer in which the iron core and winding are not immersed in insulating oil and is mainly composed of an iron core and a coil. It mainly relies on air convection for cooling and is generally used for small-capacity or medium and low-voltage transformers. Its cooling medium is generally epoxy resin. We generally choose epoxy resin as its cooling material.

 

Here are some advantages of dry-type transformers.

1. Low loss and low noise.
2. Good heat dissipation
3. Strong short-circuit resistance and good thermal stability.
4. long service life.
5. Small size and lightweight.
6. High overload capacity

It also has some disadvantages.

1. Not easy to repair.
2. It is more expensive than other transformers.

200 kVA Three Phase Distribution Transformer

200 kVA three-phase distribution transformer is a relatively common type of transformer in the entire transformer market, and it is also a type of transformer with more demand. Distribution Transformers or Service Transformers are widely used in substations of power supply and distribution systems, They can provide customers with the required voltage level.

 

Here are some advantages of three-phase Distribution Transformers.

1. For most customers, it is the most economical choice.
2. In long-distance power transportation, its high efficiency and low loss are reflected.
3. In long-distance power transportation, its high efficiency and low loss are reflected.

What is the price of the 200kVA transformer?

Although these transformers are all at the level of 200kVA the price of each type is different. For 200kVA Dry Type Transformers, the price of one unit is around 3500 USD. For 200kVA three-phase Distribution Transformers, one unit costs around 3000 USD. For 200kVA 3PH Isolation Transformers, one unit costs around 1200 USD.

 

How many amps can a 200 kVA transformer supply?

How many amps can a 200 kVA transformer supply is a technical question and we need to use a formula to get the answer. For single-phase transformers, we need to use kVA to multiply 1000 and divide the volts. For three-phase transformers, we need to use kVA to multiply 1000 and divide the volts and 1.732.

 

According to the formula, we can find that single-phase transformers’ amps are 833.33 amperes and three-phase transformers are 288.68 amperes.

How many houses can a 200 kVA transformer handle?

In North America, each house will be serviced at 240V (2 x 120V split phase) at 100A per leg. It could be 150A or 200A for bigger houses, but let’s call it 100A at 120V, times two. That’s 24kW peak power.

 

The transformer wouldn’t be expected to supply more than, say, 80%-85% of its nameplate rating in kVA because there may be voltage sag. So it is at 80%, that’s 160kVA so no more than about 15 houses.

How much does a 200 kVA transformer weigh?

Although these transformers are all at the level of 200kVA the weight of each type is different. For 200kVA Dry Type Transformers, the weight of one unit is around 1030 kg. For 200kVA three-phase Distribution Transformers, the weight of one unit is around 1130KG. For 200kVA 3PH Isolation Transformers, one unit costs around 500KG.

How big is a 200kVA transformer?

Although these transformers are all at 200kVA the size of each type is different. For 200kVA Dry Type Transformers, its length is 1200㎜, width is 760㎜ and height is 990㎜, so the size of one unit is around 0.9m³. For 200kVA 3-phase Distribution Transformers, its length is 1170㎜, width is 860㎜and height is 1160㎜. so the size of one unit is around 1.17m³. For 200kVA 3PH Isolation Transformers, the size of one unit is around 0.3m³.

How much oil is in a 200 kVA transformer?

For 200kVA three-phase Distribution Transformers, the oil in it is about 160KG.

 

What is the current rating of the 200 kVA transformer?

By assuming that it’s a three-phase transformer then the maximum current or full-load current on the 415V side is as follows.

I=200kVA/(sqrt(3)∗415V)=278.24Amps

On the other hand, if it is a one-phase transformer then the maximum current or full-load current on the 415V side is as follows.

I=200kVA/415V=481.92Amps

Does a 200 kVA transformer carry more load than a 200 kVA generator?

No, the rating is simply a part of the components specification that describes its current and voltage handling characteristics. However, it doesn’t specifically state where the limit lies, is it the limit of the core ferromagnetic material, windings, rating of the shaft of the generator, etc.? You’d also have to look at other characteristics such as current ratings, voltage ratings, temperature ratings, and temperature kVA rating indicates.

 

Generally speaking, the limits are most often a combination of several different factors, as it would be uneconomical to make say the winding capable of supporting twice the current of the ferromagnetic material.

 

What is in the nameplate of the 200 kVA transformer?

The nameplate is also an indispensable part of the transformer, let’s look at some minimum information and data printed that on a 200kVA transformer’s nameplate. it usually contains the name of the manufacturer, Product name, phases number, manufacture years, Rating in kilovolt amperes, Identification number, impedance, oil volume, BIL, total weight, Oil volume, rated high voltage, rated low voltage, frequency, bayonet fuse and current limiting fuse, energy efficiency, tap switch with corresponding position, Standard, impedance, connections diagram, physical identification, and vector diagram, manufacturer reference number.
