Gis Substation in India

A GIS substation is a type of electrical substation that uses a gas-insulated switchgear (GIS) to control and protect electrical equipment. Gas-insulated switchgear is a type of electrical equipment that uses pressurized, insulating gas to isolate and protect electrical components from the environment. GIS substations are typically used in high-voltage applications, such as transmission and distribution systems, where space is limited and environmental conditions, such as extreme temperatures or corrosive atmospheres, make other types of substations impractical.

Gas-insulated switchgear also has several advantages over air-insulated switchgear, including lower maintenance requirements and greater reliability.

The GIS substation in India is one of the most modern and efficient power plants in the country. It is located in the state of Gujarat and supplies power to the entire region. The plant has a capacity of 1000 MW and can supply power to more than 1 million homes.

List of Gas Insulated Substation in India

A gas insulated substation (GIS) is a type of substation that uses gas instead of air to insulate electrical equipment. Gas insulated substations are typically used in places where space is limited, such as underground or inside buildings. Some of the benefits of using GIS include:

– Reduced maintenance costs: Gas insulation does not require regular maintenance like air insulation does. This results in lower overall costs for maintaining a GIS. – Increased reliability: GIS are less likely to experience outages due to weather conditions or other external factors.

– Increased safety: Gas is an excellent insulator and therefore reduces the risk of electrical shock.

First Gas-Insulated Substation in India

What is a Gas-Insulated Substation? A gas-insulated substation (GIS) is a high voltage substation in which the major structures are contained within an enclosure that is filled with SF6 gas at atmospheric pressure. The first GIS was installed in India in 1974.

The technology has been continuously evolving since then and Indian utilities have installed more than 1,000 bays of GIS across the country. GIS offers many advantages over air insulated substations (AIS). These include smaller footprint, reduced maintenance requirements, higher reliability and superior safety record.

In recent years, GIS technology has evolved to meet the challenges posed by ever-increasing electricity demand and rapidly changing grid conditions. Newer generation GIS equipment can now handle voltages up to 1,200 kV and offer even greater levels of reliability and performance.

Where is India’S First 765Kv Gis Commissioned?

India’s first 765kv GIS has been commissioned in the state of Gujarat. The project was executed by Power Grid Corporation of India Limited (PGCIL).

What is Gis in a Substation?

A geographic information system (GIS) is a computer system for capturing, storing, analyzing, and managing data and associated attributes that are spatially referenced to the earth. In a substation, GIS may be used for monitoring and control of equipment, asset management, planning, and operations. GIS technology can be used to answer questions such as: Which line is most likely to fail?

Where is the closest spare part located? What is the impact of a new development on existing infrastructure? By overlaying different layers of information (e.g., roads, rivers, elevation), GIS can help identify relationships and patterns that would otherwise be hidden.

A substation typically contains high-voltage equipment such as transformers and switches that reduce the voltage of electricity before it enters homes and businesses. Substations also contain devices that measure electricity flow and protect equipment from faults.

What is the Disadvantage of Gis Substation?

There are many disadvantages of using GIS substations. One disadvantage is that they tend to be more expensive than traditional substations. Another disadvantage is that they can be difficult to maintain and operate.

Additionally, GIS substations can be less reliable than traditional substations.

What is Gis And Ais Substation?

Geographic Information Systems (GIS) and Automated Identification Systems (AIS) are two technologies that are often used together to create a complete picture of an area. GIS provides detailed mapping information that can be used to identify specific locations, while AIS gathers data about the movements of people and objects. When these two systems are combined, they can give planners and emergency responders a comprehensive view of an area, allowing them to make better decisions about how to protect and serve the public.


In India, the GIS substation is becoming a popular choice for power plants. This type of substation offers many advantages over traditional substations, including a smaller footprint, less environmental impact, and improved reliability.
