Can the SF6 leakage monitoring and alarm system detect excessive SF6 gas leakage during power outage maintenance in the substation? How to deal with SF6 gas leakage in high voltage electrical equipment? What are the sources of SF6 harmful toxic gases?
Dissemination of SF6 and tracking its dispersion in the atmosphere is a well-known technique used to predict how pollutant affects the environment. Remote thermal imaging of the atmospheric tracer plume is one of the methods employed to detect and track its dispersion. However, remote detection of...
For both slow cooling and fast cooling, we detect an absorption peak at 2 eV. Fig. 1: Phase diagram of SF6. a The generic pressure, temperature, volume (p,V,T) Gibbs surface showing the three phases, their coexistence and their boundaries. b Color plot of the isochore specific heat ...
Zero sequence current transformers are designed to detect earth leakage currents. Connect the secondary winding of the zero-sequence current transformer to the corresponding analog input of the relay protection and automation unit, and the zero-sequence current transform...

(SVM) to detect the type of insulation fault under PD9. Ding et al.found that corona discharge and spark discharge can be distinguished by testing the concentration ratio of (SOF2 + SO2)/(SO2F2)10. Their experiment indicated that the (SOF2 + SO2)/(SO2F2) concentration ratio of...
in addition to the voltage test to determine whether it can be put into operation, there is still a lack of early insulation defects detection methods and detection means. Therefore, in order to effectively detect the circuit breaker opening performance and accurately assess its arc contact deterior...
