For that reason, it is urgent to find an alternative that replaces SF\({}_{6}\) in medium voltage switchgear (MVS) before a possible ban on its use comes into force. Initially, SF\({}_{6}\) alternatives were focused on the use of existing technologies such as air-insulated switchgear (AIS) [13] or solid-insulated switchgear (SIS) [14]. Even though both have been commonly used in low-voltage equipment, their use in higher voltage systems would require higher dimensions and, therefore, higher costs. The mixture between SF\({}_{6}\) with a carrier gas, like air, N\({}_{2}\), or CO\({}_{2}\), was then considered for insulation [15]. Although the use of SF\({}_{6}\) is reduced, the environmental impact of the mixture, even with low SF\({}_{6}\) concentrations, is still significantly high. Consequently, researchers are more focused on finding other gas or gas mixtures that replace SF\({}_{6}\) completely. There are some important requirements that this gas or gas mixture must meet, according to [PERSON] et al. [16], to be considered a suitable option: high dielectric strength, good arc quenching capability, low boiling point, high vapor pressure at low temperature, high heat dissipation, and compatibility with the materials used in electrical switchgear, among others. Moreover, the gases must have low toxicity, no flammability, no ozone depletion potential (\(ODP\)), minimal environmental impact, and low \(GWP\), to meet the environmental, health, and safety requirements. The most important of these characteristics is the dielectric strength, or electric field strength (\(E_{\sigma}\)), which is defined as the maximum voltage that an insulating component can withstand before suffering electrical breakdown [17]. Currently, the different gases that are \begin{table}

Table 1: The lifetime (\(LT\)) in the atmosphere, global warming potential values in a 100-year horizon (\(GWP_{100}\)), and applications of SF\({}_{6}\) and other fluorinated greenhouse gases. being researched are hydrofluorocarbons (HFC), perfluorocarbons (PFC), fluoroketones (FK), fluoromatirles (FN), and hydrofluoroolefins (HFO) [15; 16]. HFCs and PFCs have excellent dielectric properties [2], but their _GWP_ is high, between 5000 and 12,000 in a 100-year horizon [16], making them not suitable environmentally. FKs and FNs have better dielectric properties than SF\({}_{6}\)[15]. One of the most researched FK, C\({}_{5}\)F\({}_{10}\)O, has almost the same _GWP_ as CO\({}_{2}\), but its boiling point reaches 300 K. Although FNs have higher _GWP_, they present a lower boiling point, high stability, and material compatibility [18]. Finally, a certain researched HFO, C\({}_{3}\)F\({}_{4}\)H\({}_{2}\), has slightly lower dielectric strength than SF\({}_{6}\), a low boiling point, and low _GWP_[16].
