Tungsten Copper Electrical Contacts
Tungsten copper (WCu) is used for arcing contacts in SF6 circuit breakers for ultra-high, high and medium voltage applications. At the heart of the switching chamber, WCu contacts are exposed to extreme mechanical and thermal loads: When the circuit is opened and closed, the arc starts directly at the switch contacts at a temperature of up to 20 000 °C. Tungsten-copper is popular because of its combination of unique material properties. A high level of temperature resistance is one of the most... (read more)

Moisture Measurement in SF6 - A Permanent, Environmentally Safe Solution (.pdf)
Most electric utilities and independent power producers use Sulfur Hexafluoride (SF6) as an arc quenching and insulating gas in high voltage circuit breakers and switchgear installed in their electrical transmission and distribution systems. These circuit breakers require periodic maintenance
Sulfur Hexafluoride (SF6) Insulating Gas Leak Detection with an IR Imaging Camera
For years, electric utility transmission thermographers have wanted a camera that could spot leaking sulfur hexafluoride, SF6. As an insulating gas, SF6 is widely used by the electric power industry in high voltage circuit breakers to prevent arcing. Early efforts met with limited success through
