Enhancing Corrosion Resistance of Copper for C4F7N Based Eco‐Friendly Gas‐Insulated Equipment
High Voltage, EarlyView.ABSTRACT Perfluoroisobutyronitrile (C4F7N) is recognised as the next‐generation dielectric medium for eco‐friendly gas‐insulated equipment (GIE). However, there is gas metal incompatibility in strong electromagnetic environments and environmentally friendly insulating gas atmospheres that endangers the operational safety and service life of GIE.

High Voltage, EarlyView.ABSTRACT The optical emission spectra (OES) reflect the presence of excited states in the gaseous discharge, which are directly linked to the decomposition characteristics of insulating gases. In this study, a pin/rod–plate discharge reactor driven by either a high‐voltage direct current (DC) generator or a pulsed generator was developed to establish ...
