Short Description :

Power Grid Corporation of India Limited and Toshiba Transmission & Distribution Systems (India) Private Limited have jointly introduced India's first indigenously manufactured 220kV Mobile Gas-Insulated Switchgear (m-GIS) system. This advanced, compact, and reliable system is designed for rapid deployment, significantly enhancing grid flexibility, resilience, and disaster preparedness, especially in areas with limited space. The collaboration also plans to deliver India's first indigenous 400kV m-GIS system next year.

Detailed Coverage :

Power Grid Corporation of India Limited (POWERGRID) in partnership with Toshiba Transmission & Distribution Systems (India) Private Limited (TTDI) has launched the nation's first 220 kilovolt (kV) Mobile Gas-Insulated Switchgear (m-GIS) system. This innovative system was designed and built entirely in line with POWERGRID's specific operational requirements, with TTDI handling the manufacturing.

Gas-Insulated Switchgear (GIS) is a compact and highly reliable electrical system used for safe and efficient distribution of high-voltage power. The 'Mobile' aspect of m-GIS means this system can be transported and deployed quickly to different locations, offering unprecedented flexibility.

The key benefits highlighted include rapid deployment capabilities, which dramatically enhance grid flexibility, resilience, and readiness for disasters. Its modular 'connect–disconnect–redeploy' feature ensures swift operational agility, making it a crucial development for managing emergency grid needs and ensuring continuity of power supply.

Looking ahead, TTDI has announced plans to produce India's first indigenous 400kV m-GIS system for POWERGRID, with an expected delivery in August of the following year.

Impact This development marks a significant step forward in modernizing India's power transmission infrastructure. The ability to rapidly deploy critical grid components improves response times to faults or emergencies, potentially reducing downtime and ensuring a more stable power supply across the country. It also boosts domestic manufacturing capabilities in advanced power technology. Impact Rating: 7/10

Difficult Terms: Gas-Insulated Switchgear (GIS): A type of high-voltage switchgear where all live parts are insulated by gas, typically sulfur hexafluoride (SF6). It is significantly more compact and reliable than traditional air-insulated switchgear, making it ideal for space-constrained substations. Mobile GIS (m-GIS): A Gas-Insulated Switchgear system that is housed within a mobile unit, such as a trailer or truck, allowing it to be quickly transported and set up in various locations. This provides flexibility for temporary power needs, emergency repairs, or network upgrades.
