With transformers consistently evolving, only a few manufacturers are prioritizing quality over quantity, and in the case of 14.4 kV transformers, this type of transformer is known to be produced in many numbers which is why quality control is a must for this level of transformer kV. 12.47 kV to 480v transformers and 34.5 kV to 480v transformers have also been noted for quality control as well due to massive production.

But before going through the complexity of 14.4 kV transformers, it is highly recommended to review first the basics of this transformer kV to not get confused as you go deeper into the article. DAELIM, a professional 14.4 kV transformer from China, will help you understand this by providing you with all the necessary information for this transformer kV.

For some consumers, people often think of transformer ratings differently and with a lot of variants in the market, it can be confusing which is why it is important to clearly understand transformer ratings first before going through the characteristics of 14.4 kV transformer.

For starters, you must have noticed that transformers and other powerful electric devices use kVA or kilovolt-amperes instead of kW or kilowatts. So, why aren’t transformers rated in watts? To understand this concept keep in mind that voltage ampere (VA) is equal to the Voltage multiplied by Amperage.

On the other hand, kilovolt-ampere is equal to the same formula which is Voltage multiplied by Amperage but it is divided by 1000 afterwards.

Now that you know the formula for VA and kVA, what about formulas related to watts? For watts, **Voltage Amperage** will be multiplied by the Power Factor. For kilowatts or kW, there are three elements to be multiplied and that is Voltage multiplied by Amperage multiplied by Power Factor then divided into 1000.

As you can see from the formulas above, the formulas of voltage ampere and watts are very similar. The slight difference between them is the presence of the Power Factor in the Watts formula.

In the case that the Power Factor is equivalent to 1, it is expected that the Voltage Ampere will be equal to watts. However, if the Power Factor results in 1, then there will be no utility for watts since the Voltage Ampere can also be equal to 1.

With all these data, you can conclude that the Power Factor is not the numeral 1.

The Power Factor will heavily depend on the load that is connected to the 14.4 kV transformer or generator present. Loads can actually vary like resistive, inductive, capacitive, and can be a hybrid. Transformer manufacturers will not be certain of what of you will use, it will not be possible for them to exactly know the Power Factor.

Simply take it like this, if the manufacturers know how much load there is, they will also know the Power Factor. In the case that they do not know the load, then they will not have an idea how much there is for Power Factor and Kilowatts.

For this specific reason, this is why transformers, generators, and other powerful electrical devices use kVA, not watts.

Now that you know why transformers and other powerful electrical devices use kVA instead of kW, it is time to move on to why motors use kW instead of kVA? For starters, motors and transformers are very different which means they do not belong in the category when it comes to power.

In addition to that, transformers and motors have different utilities. In terms of its formula, it is rated in watts which means you will the Watts is equal to Voltage Ampere multiplied by the Power Factor.

This goes to show that the Power Factor is known, unlike transformers. This is why you can easily add this to your voltage equation for you to solve the total Watts. This is the primary reason why motors are rated in Watts and not in kilovolt-amperes.

For many, seeing 34.5 kV to 480v transformer or 12.47 kV to 480v transformer can be intimidating and confusing. The easiest way to determine a transformer’s rating is through its size. The bigger it is, the higher their rating is, and the smaller it is, the lower the rating is its rating as well.

In general measuring, that is how you do it, but what about accurately telling a transformer’s rating? You can do so by learning the abbreviations of the units being used first, which you already know (kV, kVA, VA. etc.).

Usually, small transformers are rated in Voltage Amperes. A transformer that has a rating of 100 Voltage-amperes is capable of withstanding 100 volts that is at one ampere of current. 1000 volt-amperes is basically equivalent to 1 kVA which is the reason why small transformers use the unit of voltage-amperes only.

So how do you determine a transformer’s kVA size? For starters, you will have to create multiple calculations that is based on the principle of electrical schematics which can be confusing if you do not know the basics.

Nonetheless, the electrical load that is associated with the transformer’s secondary winding will need a certain input or voltage load. Mark that as your voltage “V”. Afterwards, you will then need to know its voltage.

Take 150 volts as an example.To know what is the current flow of the electrical load, you will need to review the electrical schematic to help you know what number is needed to proceed. If ever you will not be able to find the current flow, you can try to calculate it through division.

Dividing the input’s voltage by the resistance of the input will give the chance to determine how much load is required in kilowatts. Another equation is required for this and the formula to be used is to multiply the needed voltage or “V” by the current load that is needed that will be in amperes. Lastly, you will have to divide the number by 1000.

Lastly, you will have to divide the number by 1000.

As mentioned, with the example 150, you will multiply that number by 50 in order to get a result of 7,500. Now that you have 7,500, divide that by 1000 to achieve the result of 7.5 kilowatts. The final step would be to convert its unit from kW to kVA.

When doing this, make sure that you will divide by 0.8, because this number represents the Power Factor that is in a load. So after dividing 7.5 by 0.8, you will get a result of 9.375 and this will be in kVA.

When you are looking for a transformer, it is most likely that you will not find a transformer that is rated 9.375 kVA or below because transformers that are in a kVA rating are normally rounded off to whole numbers which means that there will be no 8.355 kVA, 7.200 kVA, and so on in the market.

Usually, you will find transformers such as 30 kVA, 40, kVA, 50 kVA, and so on in the market. Depending on what your project or purpose of purchasing a transformer is, it is recommended that you choose a transformer that a higher rating than the result of your formula.

You also have the option to work the opposite way by using the most well-known kVA transformers to calculate the amperage that you want to utilize. For instance, if your transformer of interest is rated around 1,5 kVA and you want to amp it up to be used around 20 volts, you will have to multiply somewhere around 1.0 by 1000 to get 1200-1300 then divide it by 1500 to get the result of 40-60.

This will allow you to operate your transformer around that level of amperes of current.

Medium-voltage transformers like 14.4 kV transformers are basically used for multiple industries and businesses including but are not limited to hospitals, schools, and other large establishments. Medium-voltage transformers help ensure its consumers run operations smoothly with little to no power interruptions.
