Detection of SF₆ decomposition products generated by DC corona discharge using a carbon nanotube gas sensor

Adsorptions of SO2, SOF2, and SO2F2 on Pt-modified anatase (101) surface: Sensing mechanism study

“…When partial discharge or overheating faults occur in the electrical equipment, which are usually caused by internal insulation defects, the gasinsulated SF 6 may easily decompose and produce a variety of by-products with the inevitable trace H 2 O and O 2 in the gas chamber [1][2][3]. The composition and content of these by-products can be used to determine the types, sizes, and causes of partial discharge and provide reliable information to evaluate the insulation status of the equipment [4][5][6][7][8].…”

Insulation condition monitoring of epoxy spacers in GIS using a decomposed gas CS2

“…Since the decomposition byproducts accumulate in a closed GIS tank depending on the total PD activities, the chemical methods are suitable for long-term trend-based diagnosis [9]. As an alternative way for the electrical methods, chemical byproducts analysis has been used as a powerful method for GIS diagnosis [9].…”

“…As an alternative way for the electrical methods, chemical byproducts analysis has been used as a powerful method for GIS diagnosis [9]. Some researches concluded that CF 4 was a typical gas generated by partial discharge on the spacer surface.…”

Investigation of Gas-Sensing Property of Acid-Deposited Polyaniline Thin-Film Sensors for Detecting H2S and SO2

“…Gas sensors under study for on-line monitoring and fault diagnosis of electrical equipment mainly include carbon nanotube gas sensors [12,13], titanium nanotube gas sensors [14,15], as well as graphene gas sensors [16,17]. Some research results related to GIS partial discharge monitoring field have been achieved [18].…”
