“…Thus, many contributions can be found investigating the breakdown behaviour in pure gas, e.g. [7,8,9,10,11,12,13,14,15,16], and in gas mixtures with sulphur hexafluoride (SF 6 ), e.g. [17,18,19,20], as well as concerning the properties on the molecular level, e.g.…”

In literature a model was described for the simulation of the breakdown behaviour of SF 6. As input parameters, results from swarm experiments-the critical field strength and the effective ionization coefficient-and thermodynamic properties are sufficient. Recently it was shown that it is possible to transfer this model to another strongly attaching gas. In this contribution the model is applied to tetrafluoromethane (CF 4), which has smaller critical field strength and is less attaching than SF 6. Further, the breakdown field strengths of alternating and lightning impulse voltages of different field configurations-from homogeneous to inhomogeneous fields-are predicted for CF 4. A comparison to experimental results from literature shows a good agreement. Thus, the model is applicable not only to predict partial discharges and breakdown voltages in strongly attaching gases but also to gases less attaching than SF 6 .

“…Since CCl,F, and CClHF,, are one type of CFCs and HCFCs respectively, which have been used as refrigerants, have relatively high breakdown strengths even in the gas phase [2, 3,4], there are few breakdown accidents in appliances using these substances. However, the breakdown characteristics of HFCs have not been thoroughly measured, and thus it is unknown whether HFCs have a greater breakdown strength than these two or not.…”
