GIS Decomposition Safe and efficient

Jun 13, 2017The concentrations of harmful decomposition products for AirPlus are moderately higher than for air, but significantly lower than for SF 6. The paper concludes that GIS with AirPlus is not only a step forward in terms of global warming, but also safe during operation and defect conditions.
