Transformer 2000 kVA And Its Function
An electrical transformer is a tool that converts alternating electricity from one voltage to another. It works on the magnetic flux principle and may be configured to "step up" or "step down" voltages. And the magnetic flux in the 2000 kVA transformer can cause different electromotive forces in any other coils base. Without a metallic link between these circuits, energy can be transmitted across multiple coils of the 2000 kVA transformer.
A 2000 kVA transformer is placed in areas where there is no room for a closed enclosure. All connection points in this transformer have a total load current that has been safely contained in a grounded metal casing. Typically, the 2000 kVA transformer is often utilized with underground electric power distribution cables. It can be used to serve one large building or many homes.
Electrical Capacities of a 2000 kVA Transformer
Kilovolt Ampere Rating
The kVA rating, which stands for Kilovolt-Ampere, is the most common way to grade a transformer. The kVA of the load determines the transformer size. In many cases, the load's power consumption is proportional to the transformer's rating expressed in VA or kVA. A 1KW (1000 Watt) load, for example, would need a 1kVA transformer with a unity power factor.
For three-phase KVA= (V*I*1.732)/1000
For single-phase KVA= (V*I)/1000
For three-phase MVA= (V*I*1.732)/100,000
For single-phase MVA= (V*I)/1000,000
The transformer's core directs the magnetic field path between the primary and secondary coils to avoid wasting energy. When the magnetic field reaches the secondary coil, it causes the electrons inside it to migrate. It results in an electric current (EMF). With a voltage regulator of off circuit tap changer, a 2000 kVA transformer has 10,000/400 Voltage.
Various Voltage Ratio:
- 10500/400 V
- 10250/400 V
- 10000/400 V
- 9750/400 V
- 9500/400 V
In engineering, volt-amperes are a unit used to represent the electrical load. The abbreviation for volt-amperes is VA. Metric prefixes like "kilo-" and "mega-" can also be used. One kilovolt ampere is equivalent to 1,000 volt-amperes, while one megavolt ampere is equal to 1,000,000 volt-amperes.
As a result, one megavolt ampere requires 1,000-kilovolt amperes. To convert kVA to MVA, multiply the value by 1,000. For example, if you have 438 kVA, multiply it by 1,000 to obtain 0.438 MVA. 2000 kVA then is equivalent to 2 MVA.
What Is the Difference Between an Oil Type and a Dry Type 2000 kVA Transformer?
Dry-type transformers and oil-filled transformers both serve the same goal, yet they differ significantly.
A cooling medium is required to prevent the transformer from overheating and potentially causing a fire or explosion. When transformers are under load, overheating is unavoidable. It must be addressed since temperature rises are not acceptable when transformers are in operation. Air is used to cool dry-type transformers, whereas oil is used to cool oil-filled transformers.
Some public buildings avoid using oil-filled transformers since they are a fire danger instead of dry-type transformers. It is due to the flammability of the liquid being utilized. A situation in which oil spills, seeps, or becomes polluted may quickly occur, putting the inhabitants of the building in danger. As a result, they may only be used in outdoor installations.
Oil-filled transformers, on the other hand, need more frequent maintenance than dry-type transformers. The oil must also be tested to ensure that there are no contamination issues. The dry-type is very resistant to chemical pollutants, so it won't need to be dismantled every time a little mishap occurs.
Typical Applications for 2000 kVA Transformer
Switching Current Regulation
The primary purpose of all transformers is to increase or decrease the alternating current in the electrical system. The transformer provides greater energy efficiency by controlling current flow, which regulates and eventually reduces power expenditures.
Putting a Stop to the Flow of Energy Then Resuming It
Transformers can also be used to interrupt an electric current or stop the flow of power. Transformers are frequently found in breakers, where they use a switch to halt the electric current and protect against high-voltage damage automatically.
The operation of generators fuels the notion of charging batteries. Transformers are used to regulate the voltage that enters the battery during the charging process. It prevents harm to the internal components of the battery. It is critical since an uncontrolled voltage might produce large surges during battery charging.
Production of Steel
Large electrical transformers are used in steel production plants to offer various voltages for the manufacturing process. During the melting of steel, a large voltage is necessary, whereas lower currents are required during the cooling process. Transformers are required to supply this variety of voltages by controlling currents inside the system.
Electrolysis is typically fueled by the operation of transformers in chemical design and industrial processes. Electrolysis often involves the use of metals such as copper, zinc, and aluminum. Transformers are utilized to generate a controlled electrical current to drive the chemical reaction from start to finish.
How Do You Calculate the Maximum Load of a Transformer?
The total load ampacity of a transformer specifies how many amps it can handle. It is significant because it aids in determining the transformer size required to accommodate a specific load.
To calculate the total load ampacity, use the following formula:
- KVA x 1000 / The line to Line voltage
So, for a 2000 KVA transformer, we will multiply 2000 x 1000 and then divide it by 240v.
- (2000 x 1000) 240v
That gives us 8,333 amps. So, for a 2000 KVA 240v single phase transformer, the total load ampacity is 8 333 amps.
How Much Does a 2000 kVA Transformer Weigh?
The weight of the transformer is factored into the total pricing calculation. It allows electrical contractors and transformer distributors to pay their costs and make a profit. A 2000 kVA Transformer weighs 4785 kilograms with a 1,025 kg weight of oil.
The power it is expected to carry and the voltage for which it is used determine the cable size. During expansion, the voltage drop that might flow from one end to the other must often be kept within limitations. As a result, cables must be chosen with these factors in mind on both the HV and LV sides.
The capacity of the cable to transport current:
The full load current of a transformer is computed as follows
- Full-load = 12.5 × 106 / 1.73 × 20 × 103 = 361 A
What Does kVA Mean in Transformers?
Kilovolt-Ampere (kVA) is the unit of measurement used to grade transformers. The kVA of the load determines the size of the transformer. In many cases, the load's power requirements are equivalent to the transformer's rating stated in VA or kVA. A 1KW (1000 Watt) load, for example, would need a 1kVA transformer with a unity power factor.
Copper Losses are determined by the current that flows through transformer windings. Whereas Iron Losses, Core Losses, and Insulation Losses are determined by voltage.
What Causes Transformers To Hum?
The continuous expansion and contraction of the steel core inside the transformer causes it to hum. The quantity of flux determines core expansion, determined by the applied voltage and the number of turns in the transformer coils.
Why Are Transformers Measured In Kilovolt-Amperes (kVA)?
The power factor of the input and output supplies is always the same. And the power factor of the input supply does not affect the losses in the transformers.
How Can Core Losses Be Minimized?
Transformers are constructed using higher-grade steel (usually Cold Rolled Grain Oriented –CRCO) to decrease core losses.
Electrical transformers significantly influence our everyday lives, especially in creating and delivering electricity to your household appliances. You can improve the efficiency and longevity of your devices by selecting the appropriate transformer. The 2000 kVA Transformer is no different.
