Gas-Insulated Substations - GIS

A gas-insulated substation (GIS) uses a superior dielectric gas, insulating gas, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in Sulfr hexafluoride gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what Sulfr hexafluoride can do in centimeters.

gaz sf6 Monitoring System for GIS – GE Grid Solutions

SF 6 Monitoring System for GIS. With worldwide scrutiny on SF 6 gas usage, increased environmental reporting requirements and even possible penalties, precise early detection of small gas leaks in Gas Insulated Substations that use so much SF 6 is essential. The B Watch uses the latest generation of EMC resistant digital gas sensors to continuously measure gas pressure and temperatures in order to track changes in density and detect gas leaks down to 0.1% per year.

Analysis of insulating gas Insulation Gas Using a GC-BID System

Insulation Gas Using a GC-BID System. Sulfur hexafluoride (SF 6) is an extremely stable gas with excellent dielectric properties and is used in various fields. Applications include tracer gas as well as insulation gas used in electrical equipment such as gas-insulated transformers and circuit breakers. On the other hand, SF 6 is also known to be a highly potent greenhouse gas and was identified as an emission reduction target in the Kyoto Protocol at the COP3 meeting.
