Glossary of Medium Voltage Switchgear Terms· GIS equipment is a type of metal-clad switchgear construction, where all the switchgear power components are located inside of a sealed metal envelope filled with (usually) SF6 gas. GIS equipment is often supplied into high voltage applications, but there are now offerings at medium voltage.
Vacuum interrupter role in transformer on load tap changer ...· The use of a vacuum interrupter as a tap changer inside oil-filled transformers has been employed since the 1960s. The fully enclosed arc chamber of the vacuum interrupter proves to be a major advantage. When the vacuum interrupter opens while changing the taps,the resulting arc is fully contained and does not contaminate the oil with …
