Abstract

SF₆ gas is a chemically stable substance known for its excellent arc-extinguishing performance and insulating properties. It is currently widely used in high-voltage electrical equipment such as Gas-Insulated Switchgear (GIS) and Gas-Insulated Lines (GIL) chambers, playing a crucial role in enhancing power transmission capacity and the miniaturization of electronic devices. However, SF₆ gas has its limitations and is classified as a controlled greenhouse gas. Consequently, there is a growing focus within the high-voltage electrical equipment manufacturing industry on new environmentally friendly insulating gases that can effectively replace SF₆. The adoption of these new insulating gases, particularly in high-voltage electrical equipment, is on the rise. To ensure the reliable operation of density relays, research and the application of intelligent calibration for density relay devices using novel insulating gases are of significant importance.
