Study on surface flashover characteristics of basin-type insulators under low-frequency transmission based on multiphysics coupling

Zhejiang dianli
To study the surface flashover characteristics of single-phase basin-type insulators in gas insulated metal-enclosed switchgear （GIS） under low-frequency transmission， an electro-thermal-fluid coupling simulation is employed.

Construction of abatement cost curves: The case of F-gases [PDF]

Most of scientific research on Greenhouse Gases (GHG) focuses on CO2 emissions. But non-CO2 gases (mainly F-gases in the form of HFCs, PFCs, and SF6) are more potent at trapping heat within the atmosphere. Currently, F-gases constitute a small proportion
