The Problem with Humidity in insulating gas Gas-Insulated Systems

To prevent operational and safety issues, it is important to measure and monitor humidity levels in gas-insulated switchgear (GIS). Due to its excellent dielectric capabilities, sulfur hexafluoride (SF 6) is the preferred insulator in electrical transmission and distribution equipment. Switchgears insulated with SF 6 gas are tightly sealed. However, over the lifetime of the equipment, impurities may find their way into the gas compartment via hoses, gaskets, and gas handling equipment.

What Are The Major Natural Resources Of El Salvador? - WorldAtlas

Geothermal EnergyForestsArable LandWater BodiesOne of the main natural resources in the country is its geothermal energy. El Salvador is one of the largest producers of geothermal energy in the world, with its peers in the geothermal generation being Costa Rica and Iceland. The huge geothermal potential is not exclusive to El Salvador as its neighboring countries are also known for their geothermal energy. Central America lies in a region which has constant tectonic activity, where the North American, Caribbean, and Coco plates are constantly colliding. The result of these tectonic movements is volcanic activity from which geothermal energy is generated. The government of El Salvador realized the huge potential in its geothermal energy sources and invested (particularly since 1990) in tapping into geothermal energy as a way of generating electricity. As a result, the country ranks as the top geothermal generating countries in the world, and geothermal power is responsible for a quarter of El Salvador’s electricity. The country’s...
