Main Component of 100 KVA 11/0.38KV Transformer

Core：

The iron core is one of the most basic components of the transformer, and it is the magnetic circuit part of the transformer. The primary and secondary winding of the transformer are all on the iron core. In order to improve the magnetic permeability of the magnetic circuit and reduce the eddy current loss in the iron core, the iron core is usually made of 0.35mm silicon steel sheet with insulating surface. The iron core consists of two parts, the iron core column and the iron yoke. The winding are put on the iron core column, and the iron yoke connects the iron core to form a closed magnetic circuit.

Winding：

The winding is also one of the most basic parts of the transformer. It is the circuit part of a transformer, usually made of copper or aluminum wire wrapped in insulating paper. The winding connected to the high-voltage network is the high-voltage winding, and the winding connected to the low-voltage network is the low-voltage winding.

Transformer leads：

1. Transformer leads have three requirements: (electrical performance), (mechanical strength) and (temperature rise requirements).

2.The power transformer leads are (bare copper wire), (paper-wrapped round copper wire), (bare bus bar), (cable) and (copper tube), etc.

3. Our factory adopts lead connection method (brazing) (gas welding) (cold pressure welding) (mechanical connection).

Oil Tank:

The basic functions of transformer oil tank can be summarized as protection of oil tank and holding oil, installation skeleton of external components and heat dissipation.

What is a 100kVA transformer?

To know about 100kva transformers, we need to figure out the differences between 100kW transformers and 100kVA transformers. Kw is short for kilowatt and is a unit we often see on our electrical paying bills. kw means the actual power or working power of the electrical devices. It is not very likely to be a 100kW transformer. But in transformers or generators, kVA is frequently used. The formula of converting kVA into kW is: kVA(apparent power)*pf(power factor)=kw(actual power)

100kVA transformers can be used on many electrical occasions like suburban areas, residential areas, commercial centers, farmhouses, industries, energy stations, and so on.

100 kVA transformer types

For GNEE transformer, 100kva transformers can be overhead transformers, single phase transformers, three phase transformers, distribution transformers, and dry-type transformers. These types of transformers are of the same principles, but they are built in different constructions, and different types of transformers have different applications. According to different occasions where you want to use your transformers, GNEE offers you ideal solutions.

At the same time, 100kVA transformers can also be divided into step up transformers, step down transformers. A step down transformer distributes primary voltage to lower secondary voltage. So the coil number of primary voltage is more than that of the secondary voltage, which means, the ratio of primary and secondary windings is bigger than 1. On the contract, a step-up transformer transforms low voltage into higher voltage, so the winding numbers of primary voltage are less than the secondary voltage, and the winding ratio of primary and secondary voltage is less than 1.

How many amps can a 100 kVA transformer handle?

Amp is short for ampere, as we have mentioned before, it is the unit of the electrical current. 1 kVA usually represents 1000 volt-amps. Volt-Ampere is equal to a Watt. We can see that to convert kVA into amps, we also need to know volts. Here is a formula we can use: I (amps)= S (VA)/ V (volts). By this formula, we can turn kVA into amps. Here are some examples of the amps of different volt:

1 kVA to amp (120V)= 8.33A

1 kVA to amp (220V)= 4..55A

1 kVA to amps (12V)= 83.33A

Let's take the voltage as 220v (frequently used), amps of 100kVA will be about 455A.

100 kVA Transformer Load Capacity

Most time, we can clearly know about the rated capacity of the transformer, which is often based on kVA. It is also important for customers to know what the load capacity means to a transformer. The load capacity of a transformer tells how many amperes a transformer is designed to load. To know about the load capacity of the transformer, you can confirm if your transformer is too big or small in size. To calculate the load capacity of a transformer, you need to know the line voltage of the secondary output of the transformer, and if it is a single phase transformer or a three phase transformer. The formula of the calculation is kVA*1000/secondary voltage. After knowing this information, you can get started. Taking the secondary voltage as 240v for a single phase transformer, we can calculate that the full load capacity is 416.67 amps. For a 3-phase transformer, let's take the secondary voltage as 120/208v, the formula will be kVA*1000/voltage*1.732. By this, we can calculate the load capacity as 277.58 amps.

How do I choose a 100 kva transformer?

When you choose a transformer, the first thing you should think about is what are you going to do with those transformers. 100 kVA is a relatively small size, so they are one of the best-selling of both business buyers and personal clients in Daelim Transformers. For 100kva pole mounted transformers, they are widely used in suburban areas, farmhouses, ranches, and some other places similarly. And 100 kVA pad-mounted transformers are more widely used in residential areas, uptown areas, parks, commercial areas, schools, hospitals, etc. Besides, we can also customize the specific transformers based on customers' needs. And the price of the transformers will be based on the needs of customers.

The specification of a transformer contained many items. It is difficult to give a specification without clear technical data because customers' needs usually design transformers' specifications are different international standards. For the GNEE transformer, 100 kVA transformers can be 100 kVA pole mount transformers, 100kVA single phase pad-mounted transformers, 100kVA three phase transformers, and 100kVA dry type transformers.

We also make ideal solutions for solar power, wind power, energy storage, mining industries, cryptocurrency, and utilities. No matter when you need solutions for your projects, we are always here.

What is the load capacity of a 100 kVA transformer?

So, for a 100 KVA transformer we will multiply 100 x 1000 and then divide it by 240v. That gives us 416.67 amps. So, for a 100 KVA 240v single phase transformer the full load ampacity is 416.67 amps.

How many houses can a 100 kVA transformer handle?

8 - 500 kVA connects a nominal number of 103 customers, 100 kVA connects 14 customers.

What is the primary current of a 100 kVA transformer?

It's rating is 100 KVA. Using the aforementioned formula, let's confirm this rating: Primary Voltages or High Voltages (H.V) is 11000 volts. Primary Current (current on High Voltage side) is 5.25 amps.

How many amps can a 100 kVA 3-phase transformer handle?

Taking the secondary voltage as 240v for a single phase transformer, we can calculate that the full load capacity is 416.67 amps. For a 3-phase transformer, let's take the secondary voltage as 120/208v, the formula will be kVA*1000/voltage*1.732. By this, we can calculate the load capacity as 277.58 amps

What is the maximum efficiency of a 100 kVA transformer?

A 100−kVA distribution transformer has a maximum efficiency of 98% at 50% full-load and unity power factor.

How to size a transformer for a house?

To determine the required transformer VA, multiply the secondary voltage by the required amperes: For example, VA=Volts x Amperes or 28V x 1.2 amperes = 33.6 VA. To determine the maximum transformer current, divide the transformer VA by transformer secondary voltage.

How much oil is in a 100 kVA transformer?

1-2. 33kV - 400/230V

What is the full load of a 100 kVA transformer?

100 KVA transformer load capacity in kW
1, transformer output power is the apparent power, and active power (KW) relationship is: apparent power = active power x power factor.

2, with the average power factor of 0.8 calculation,a 100 KVA transformer can provide (100 KVA × 0.8) 80 KW active power for the load.
