The transformer is a static device that transfers electric power from one circuit to another through the use of electromagnetic induction. There are two types of transformers: power and distribution. While both serve the same purpose, they have important differences. This article will explain the key differences between power and distribution transformers.
What is Power Transformer?
- Power transformers are a critical component of many electrical systems. They are used to regulate and maintain power levels and prevent power outages.
- Power transformers essentially contain two or more coils that enable electricity to be converted from one voltage level to another. Power transformers allow you to use the same electric device but in different locations with different voltage levels.
- Power transformers also increase safety by helping isolate the system from dangerous fluctuations in voltage, as well as providing surge suppression against lightning strikes. Without power transformers, electrical systems would be much less reliable and efficient.
What is Distribution Transformer?
- Distribution Transformers are an integral part of the electrical grid system, responsible for reducing the high voltage from a distribution line to a safe level before entering homes and commercial buildings.
- Distribution transformers are designed with an optimum net efficiency so that minimal losses are experienced in between power transmission and distribution.
- This helps to reduce electricity bills by conserving energy, thereby protecting the environment from hazardous pollutants generated due to the extended use of non-renewable power sources. The distribution transformer plays a critical role in our sustenance and is indeed a must-have component of all energy supply systems.
Difference between Power Transformer and Distribution Transformer
Power transformers and distribution transformers have their differences and defining which one is the best for any particular application can be tricky.
- Power transformers are typically used to transmit large amounts of power from generating stations and substations over long distances. Power transformers are designed for higher voltage levels than distribution transformers, which generally require a much lower voltage.
- Distribution transformers convert electricity into a form suitable for commercial or residential use near motor loads, such as electric motors, appliances, and lighting fixtures in residential, commercial, or industrial settings.
- Distribution transformers can also be used with industrial equipment that requires more frequent startup services due to their lower impedance requirements.
- Power Transformers are substantially larger than those of the distribution type because they need increased thermal dissipation in order to handle the amount of electricity supplied by power plants while distribution types must be sized according to their load conditions.
Power transformers rely on core damping methods while the most common distribution transformer utilizes air core design since it has minimal reactance.
Conclusion
Power transformers and distribution transformers are both important for the electrical grid, but they serve different purposes. Power transformers increase or decrease the voltage of electricity so that it can be sent through the power lines at a consistent level. Distribution transformers step down the voltage so that it is safe for homes and businesses to use. They also help to isolate faults in the electrical grid.
