sensors for gas-insulated switchgears (GIS) The main area of application for the non-flammable gas sulphur hexafluoride (SF 6) is insulation of electrical high-voltage switchgears, transformers and cables. Although sulphur hexafluoride is non-toxic and non-flammable, its global warming potential is about 24,000 times higher than carbon dioxide (GWP=23,900).

    High-voltage switchgear was invented at the end of the 19th century for operating motors and other electric machines. The technology has been improved over time and can now be used with voltages up to 1,100 kV. Typically, switchgear in substations are located on both the high- and low-voltage sides of large power transformers. The switchgear on the low-voltage side of the transformers may be located in a building, with medium-voltage circuit breakers for distribution circuits, along with

As mentioned above, the UE Systems Ultraprobe® 100 Leak Detector & Valve Tester utilises ultrasound technology allowing it to find compressed air and steam leaks as well as prevent machine failure. It features an eight-position sensitivity dial with decibel indications, as well as an LED bar graph for which each LED light equates to approximately 3dB. The LED bar graph can be used to calculate decibel levels. Changes in ultrasound emissions can indicate an impending problem. Early detection of this change allows the user to affect the necessary repairs before the issue becomes critical, thereby saving money and reducing downtime. As ultrasound is directional and localised, the individual is able to pinpoint the source of this...
