The “ISTE STUDENT CHAPTER” in association with IEEE at St. Joseph’s College Of Engineering, specializing in the Department of Electrical and Electronics Engineering at St. Joseph’s College of Engineering organised an eminent webinar TECHNICAL SPOT on TRANSITIONING BETWEEN GIS AND AIS – A COMPREHENSIVE EXPLORATION OF SUBSTATION TECHNOLOGIES AND EQUIPMENT on 30th May, 2024 between 6.00 pm and 7.00 pm under the auspices of Mr. Gowtham Raj, Secondary Design Engineer, Substation (Protection and Control). This impactful session delved into the multifaceted advantages of vision, emphasizing its significance across various domains. The session on transitioning between Gas-Insulated Substations (GIS) and Air-Insulated Substations (AIS) was a comprehensive exploration of substation technologies and equipment, successfully covering the critical aspects of both systems. Participants gained insights into the fundamental roles and components of substations, with detailed discussions on the advantages of GIS, such as space efficiency and reliability, contrasted with AIS benefits like cost-effectiveness and ease of maintenance. The session highlighted recent technological advancements, emerging trends, and the integration of digital technologies in substation design. Challenges and solutions in transitioning from AIS to GIS were addressed, supported by case studies and real-world applications that provided practical perspectives. An e-Memento was presented to the speaker during the session and the session ended with the online group photo.
