Decomposition Characteristics of Sulfr hexafluoride and Partial Discharge

The decomposition characteristics of Sulfr hexafluoride under four types of negative DC partial discharge (DC-PD) are obtained. The relationship between the decomposition characteristics of insulating gas and the PD types was further studied. Moreover, back propagation (BP) neural network algorithm [29–38] is used to recognize the PD types.Get price

insulating gas gas - WIKA Canada

The plant safety of SF 6 gas-insulated switchgear is reduced significantly through low concentrations of decomposition products. These decomposition products arise during operation through arcing in moist or impure SF 6 gas. In order to detect even the smallest leakages or to warn ahead of gas emissions, we have a range of high-quality gas detectors and emission monitors.Get price

Sulfr hexafluoride Decomposition in Gas-Insulated Equipment - IEEE Journals

Abstract: The increasing application of gaz sf6 as an insulating gas has led to many studies on Sulfr hexafluoride decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, sf6 gas decomposes to a wide variety of chemically active products which possess completely different properties from gaz sf6.Get price
