The power network parameter is further classified into two categories. In this substation, the synchronous condenser is used as power factor improvement equipment.

To improve the power factor, the power factor correction substation is installed. The converting substation is used in traction, electroplating, electric welding, etc. This substation changes the AC power into a DC power. Switchgears are an integral component of this substation. In case of faulty or abnormal conditions, switching substation isolates and recovers faults in power system. To overcome this risk frequency changer substation is installed to maintain frequency requirement. In industrial regions, specific frequency has to maintain and protect equipment from malfunctioning. In this substation, electrical transformer plays the major role to step up and step down the voltage. This substation adjusts the voltage level as per voltage demand. So to handle these changes, adaptive substations are commissioned. Power requirement is ever changing phenomenon in real world. And distribustion substation is part of the indoor type substation. The above three (step-up, primary, secondary) substations are the outdoor type substations.

The distribution substation receives high power from the secondary substation. This is a pole-mounted type substation that is placed near the consumer ends. It is a part of the indoor type substation. The above primary and secondary substations are outdoor-type substations.Ī distribution substation is also known as a step-down substation. Mainly, the secondary substation operates at extra high voltage (i.e. It is located at the power generation system. This substation balances the power generated and feeds power to load centers. Step-up power transformer plays a vital role in stepping up voltage levels as per requirement. It is associated with generating stations. This stepped-up load is directly fed to load centers for power transmission. This substation increases (or steps up) voltage from a lower level to an expected higher level. This type of substation operates above the 400 kV voltage range. The extra high voltage substation can handle voltage in range of 132 kV to 400 kV. The high-voltage substation can handle high voltage in range of 11 kV to 66 kV. Now based on power load requirement, there are three types of substations: However, the disadvantage is an outdoor substation needs additional protection against lightning, dust, etc. Because, it can be easily expanded to handle the increased load. Outdoor substation enjoys scalability as an advantage.

This substation is preferred for the 33kV and above voltage requirement. It is also placed in the primary and secondary transmission systems.

The foundation-mounted substation is placed in a secondary distribution system. It is placed and installed on an electric pole. Pole mounted substation is a type of distribution substation. The outdoor substations are installed where we need to generate a high voltage (for example 66 kV, 132 kV).Īccording to the construction and service, outdoor substations are further classified into two subclasses. This type of substation takes less space. These substations are constructed for low voltage requirements (for example 11 kV). Indoor substations are usually found in urban areas. One is an indoor substation and another is an outdoor substation On the basis of design, there are classified into two types. Let’s study the features and functions of each substation one by one. Those parameters are construction, service requirement, operating load, working role, and power network. There are parameters to classify substations into different categories. Now let’s study at, What are the different types of Electrical Substation? There are different types of substations designed as per the requirements. In layman’s terms, the substation is an assembly of electrical devices that are installed to control and facilitate the transmission and distribution of power.Īnd by electrical devices, I mean different types of transformers, several switchgear devices like as circuit breakers, fuse, busbars, lightning arresters, protective relays, control panels, and many more equipment are used for installing substations. The primary purpose of a substation is to provide continuous power from generating stations or transmission systems to consumer loads.

What are the different types of Electrical Substation?Īn electrical substation is an integral part of power system mainly the generation, transmission and distribution power system.
