SF6 Gas Solutions

WIKA’s Innovative Dehydrator Removes Moisture from SF6 Gas Without Stopping Operations

05/03/2019 | Leo Lopez
Wide shot of a power plant under a blue sky.

Pure SF 6 is an excellent insulator in electric switchgears, but humidity in the gas decreases its insulating ability and can also result in very harmful decomposition products for humans, machinery, and the environment. Created in partnership with a European utility …

GPU-2000: An All-in-One Solution for SF6 Handling, Replacement, and Cleaning

04/19/2018 | Leo Lopez
Transformer substation

The level of humidity in SF 6 -insulated switchgear must be kept below its water saturation point. If the gas is too humid, it loses some of its insulating properties; corrosion and dangerous leaks can also occur. A complete SF 6  handling instrument monitors the …

Water: The Most Powerful Impurity in SF6 Gas-Insulated Switchgear

04/17/2018 | Leo Lopez
Water droplets

Sulfur hexafluoride is the gas most commonly used as insulator in power transmission and distribution switchgear. Water, however, can negatively affect the dielectric capabilities of SF 6  gas. To prevent operational and safety issues, it is important to measure and …

How Changes in Gas Temperature Affect Gas Density Measurements

12/15/2016 | Leo Lopez

Circuit breakers, disconnectors, and switchgear in power transmission and distribution (T&D) operations have been using sulfur hexafluoride (SF 6 ) as insulation for decades. To maintain the excellent thermal conductivity and dielectric strength of SF 6 , …

How Ambient Conditions Can Compromise Density Measurements in T&D SF6-Insulated Equipment

12/13/2016 | Leo Lopez

For decades, the power transmission and distribution (T&D) industry has been using sulfur hexafluoride (SF 6 ) as the insulator in circuit breakers, disconnectors, and switchgear. The heat transfer and dielectric characteristics of this gas are better than those of …
