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

The Impact of Various Contact Structures on the Microscopic Surface Condition of Vacuum Interrupters During Capacitive Switching

High Voltage, EarlyView.
ABSTRACT The double‐break vacuum circuit breakers (VCBs) that utilize series break technology effectively increase the switching capability for capacitive currents, elevate the withstand voltage level, and reduce the likelihood of restrike, all without compromising the breaking capacity for short‐circuit currents.
