A substation is an installation that interconnects elements of an electric utility's system. These elements can include generators, transmission lines, distribution lines, and. A substation performs a major role in our power system. The functions of a substation may include one or more of the following: 1. To isolate a faulted elementfrom the rest. There are many kinds of ac substations. They are classified into different types based on various criteria. Some of them are discussed below. 1. Generating station substationstransform. An electrical substation contains many types of equipment. Substation generally comprises the following equipment: 1. Power Transformers. The neutral grounding resistor provides resistance grounding of the neutral transformers to limit ground fault current to a value that does not damage generating, distribution, or other associated equipment in the power system, yet allows sufficient flow of fault current.

What is an electrical substation?
An electrical substation is an integral part of a generation, transmission and distribution system. A substation can interrupt or establish electrical circuit, change the voltage, frequency or other characteristics of electrical energy flowing in the circuit.
Substations can be generally divided into three major types (according to voltage levels): Transmission substations integrate transmission lines into a network with multiple parallel interconnections, so that power can flow freely over long distances from any generator to any consumer. This transmission grid is often called the bulk power system.
Do substations have generators?
Substations do not (usually) have generators, although a power plant may have a substation nearby. A typical substation will contain line termination structures, high-voltage switchgear, one or more power transformers, low voltage switchgear, surge protection, controls, grounding (earthing) system, and metering.
What equipment is used in a substation?
To fulfill the function of a substation, they include a wide variety of equipment. Each of them will be explained in the next subsections. Power transformers are the most important equipment in an electrical substation. They are different from distribution transformers. They perform different functions. They are used to
Substation are used to transform the voltage with power transformer. From low voltage to high voltage at the power plant with breaker and control system to be able to transport the energy, and other substation at the arrival to decrease the voltage.
What are the components of a substation?
A typical substation will contain line termination structures, high-voltage switchgear, one or more power transformers, low voltage switchgear, surge protection, controls, grounding (earthing) system, and metering. Other devices such as power factor correction capacitors and voltage regulators may also be located at a substation.
