Working Principle of insulating gas circuit breaker: In the closed position of the Sulfr hexafluoride circuit breaker, the contacts remain surrounded by sf 6 gas at a pressure of about 28 kg/cm2. When the breaker operates, the moving contact is pulled apart and an arc is struck between the contacts. The movement of the moving contact is synchronised with the opening of

In discussions on climate change, we tend to focus on carbon dioxide (CO 2) – the most dominant greenhouse gas produced by the burning of fossil fuels, industrial production, and land use change.We cover CO 2 – global emissions, annual, cumulative, per capita, and consumption-based emissions – in great detail in our CO 2 emissions page.
