WIKA Canada Model GIR-10 SF6 Gas Leak detector / sniffer ... gas detector model GIR10 is used for the detection of the smallest SF 6 gas concentrations and is thus ideal for detecting the place and size of leakages.. Infrared technology The GIR10, which is based on the non-dispersive infrared technology (NDIR), offers fast response times and reliable measured values even in case of small leakages.
Power Transmission | Offerings | Siemens Energy Global for future tasks Various factors will dominate the power transmission market in the years to come: the drive toward renewable energy, the expansion and interconnection of grid infrastructures, and the need to gradually replace and upgrade aging grid infrastructures.
Switchgear | ABB help plant operators understand how digital switchgear can help overcome the hidden costs of traditional switchgear by improving your ability to collect, access, analyze and take action on the data your equipment and infrastructure creates, helping you achieve cost savings of up to 30 percent.
FLIR GF306 SF6 Optical Gas Imaging Camera | FLIR Systems FLIR GF306 optical gas imaging camera visualizes sulfur hexafluoride (SF6) and other gas emissions without the need to shut down operations. SF6 is used in the electric power industry as an insulator and quenching medium for gas-insulated substations and circuit breakers. The portable, non-contact GF306 allows you to quickly scan substations for leaks while maintaining a safe distance from ...
Insulator (electricity) - Wikipedia(electric)An electrical insulator is a material in which the electron does not flow freely or the atom of the insulator have tightly bound electrons whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field.This contrasts with other materials, semiconductors and conductors, which conduct electric current more easily.
Eco-efficient gas-insulated switchgear - Hitachi ABB Power ... fluoroketone-based SF6 alternative gas mixture is a chemical compound developed for switchgear applications by Hitachi ABB Power Grids in collaboration with 3M. It has a dielectric performance similar to SF6 when utilized in indoor applications, but with very low Global Warming Potential (GWP)*.
