MV Air Insulated and Gas Insulated Switchgear Explained


Discover the differences between MV air insulated (AIS) and gas insulated (GIS) switchgear for medium voltage power system applications. In this informative video, Eaton’s expert Matt Koepke discusses the advantages and application considerations for large power systems, including commercial buildings, stadiums, arenas, oil and gas facilities, chemical plants, industrial plants, and utility systems.

At Eaton’s Power Systems Experience Center (PSEC), Matt showcases various demonstrations and features of MV switchgear, such as self-racking, remote racking, voltage monitoring, control power transformers (CPT), voltage transformers (VT), potential transformers (PT), MV control, fuses, corona detection, Eaton’s InsulGard, protective device relays, coordination, XGIS, metering, pad-mounted solutions, e-house installations, integrated power assemblies (IPA), arc flash considerations and solutions, VCP-W, 5 kV, 15 kV, and 38 kV options.

The video also covers topics like metal-clad and metal-enclosed circuit breakers, breaker positions, control functions (open, close, charge control), current transformers, grounding and maintenance practices, arc resistance, interlocks, lockout-tagout (LOTO) procedures, electrical safety, vacuum breakers, SF6 gas usage, electrically safe work conditions, thermal monitoring, voltage sensing, and various industry standards such as IEEE, ANSI, NEMA, and IEC.

Watch this comprehensive overview to make informed decisions when selecting the most suitable MV switchgear for your specific electrical requirements and safety considerations.
