Partial Discharge Measurements in a High Voltage Gas Insulated Transmission Line Insulated with CO2 [PDF]
Energies, 2020 This paper uses practical experimentation to analyse the effect of replacing SF6 with pure CO2 in conventional gas insulated transmission line sections by studying partial discharge measurements taken with applied voltages up to 242 kV (rms). The results can also help in understanding the properties of new alternative gas mixtures which can be utilised
