There are three primary types of voltage transformers (VT): electromagnetic, capacitor, and optical.
What is the purpose of a transformer?
Transformers are employed for widely varying purposes. For example, a transformer is often used to reduce the voltage of conventional power circuits to operate low-voltage devices and to raise the voltage from electric generators so that electric power can be transmitted over long distances.
What is called mobile substation?
A mobile substation is a self-contained trailer or container equipped with the necessary high and medium voltage components of a full substation, including power transformer, switchgear and disconnect switches (GIS, AIS or Hybrid), metering transformers, surge arresters, protection and control equipment, AC and DC

Which transformer is used in substation step up or step down?
An autotransformer is a single, tapped inductor coil used to step up or step down voltage like a transformer, except without providing electrical isolation. A Variac is a variable autotransformer.
Which type of transformer is used in?

What are the different types of substation?
The different types of substations mainly include Step-up Type Substation, Step-down Transformer, Distribution, Underground Distribution, Switchyard, Customer Substation, and System Station.
How many types of electrical substations are there?
Illustrated Glossary » Substations Substation Types: Although, there are generally four types of substations there are substations that are a combination of two or more types.
What are the three main parts of a substation?
- Transmission. A transmission substation connects transmission lines, generally when all the lines concerned have the same level of voltage.
- Distribution.
- Collector.
What is the main purpose of substation?
The purpose of a substation is to 'step down' high voltage electricity from the transmission system to lower voltage electricity so it can be easily supplied to homes and businesses through our distribution lines.
Which transformer is used in sub station?
Substation transformers are most often offered with one of 3 different fluids: Mineral oil or silicone transformer oil. Primary voltages of a substation transformer usually ranges from 2.4 kV to 69 kV in 225 through 20,000 kVA sizes, but 600 volt through 35 kV secondary voltage ratings are also available.
