Sulfr hexafluoride Decomposition in Gas-Insulated Equipment - IEEE Journals

This paper reviews previous research in Sulfr hexafluoride decomposition relating to the operation of gas-insulated switchgears, gas-insulated transmission lines, and electrostatic accelerators. Results on the qualitative and quantitative determination of the by-products and their formation ion rates in various modes of electrical discharges are summarized. The mechanisms leading to the formation of transient and stable products are described.Get price

Sulphur hexafluoride gas decomposition products of fixed

Abstract: A reliable diagnostic technique of Gas insulated switchgear condition monitoring is used in this research for the detection of Sulphur hexafluoride gas (Sulfr hexafluoride) decomposition products due to its high sensitivity and anti-electromagnetic interference; it is known as decomposition by-product method. A simulated coaxial decomposition chamber was designed and used to simulate the decomposition of insulating gas under the effect of fixed metallic artificial defect on the surface of the spacer at theGet price
