From 2004 through to 2019, Coriolis Systems was a software company that supplied Mac utility software, including its award-winning iPartition partitioning tool and iDefrag disk optimizer, as well as a handful of other products including VMOptimizer, Zipster and a real time AC-3 compatible encoder, Aura. This used to be its website.
1. Gas Insulated Switchgear (GIS) or Air Insulated Switchgear (AIS)
Uses atmospheric air as insulation; requires large footprints and visible overhead busbars. GIS: Uses sulfur hexafluoride ( SF6cap S cap F sub 6
Maintain strict "Safe Working Distances" from energized busbars to prevent flashover.
Visiting requires hard hats, high-visibility vests, and steel-toed dielectric boots.
A dense copper mesh (earth mat) is buried underground to protect personnel from step and touch voltages. 🏗️ Technical Specifications (Typical) Standard Value Incoming Voltage 400,000 Volts (AC) Cooling Method ONAN/ONAF (Oil Natural Air Natural/Forced) Insulation Medium Porcelain/Composite for AIS; SF6cap S cap F sub 6 Busbar Configuration Double Main and Transfer (for high reliability)
Automatically interrupt current during a fault (short circuit) to prevent equipment damage.
Equipped with massive and oil-cooling systems to manage heat. 3. Circuit Breakers & Isolators
