At A Glance

Gas-Insulated Substations (GIS) and Gas-Insulated Lines (GIL) offer many benefits including compact size, modularity, physical security and protection from pollution and harsh environments. They also present unique challenges in how to reduce SF6 emissions and effectively detect and locate defects. EPRI research is addressing this need through laboratory tests in representative defects. The value provided will be practical and well-informed guidance on GIS and GIL application, use, and management. The GIS and GIL research is focused on two key areas: SF6 alternatives and condition monitoring of GIS/GIL systems.

Research Highlights

EPRI Guidebook on GIS and GIL – 2024 update: In 2024 EPRI will utilize its GIS laboratory to introduce typical defects and assess technologies to reliably detect these defects while the GIS is live. The findings will help the industry in specification and interpretation.

SF6 Alternatives – update on EPRI research and industry trends: In 2024 in depth and valuable insights will be provided on this important topic of alternatives. The findings will guide the industry on how to best respond to the ever-increasing pressures to reduce SF6 emissions and usage.

SF6 leak detection: It’s often difficult to pinpoint SF6 leaks at height without an outage and scaffolding. 2024 research will explore the opportunities and challenges UAVs offer in taking a leak detection payload safely to heights while a substation is energized.
