Calculating Electric Flux of Non-Uniform Electric Fields for Corona Discharge of Freon Gas

Abstract

This paper examines the self-breakdown of voltage effort in short gaps and mm of flat-out electrical electric poles filled with Freon gas at pressures ranging from 0.5–3 bar. The characterization of electrical breakdown in compressed Freon gas can be studied theoretically. Freon gas can be used as an electrical insulator alone or mixed with Sulphur hexafluoride gas, in order to reduce the cost and obtain a strong insulator at a lower cost, as Freon gas is less insulating compared to Sulphur hexafluoride gas. A proposed formulation of results is presented to make use of gas in the design, insulation, electrical appliances and equipment. Theoretical conclusions on the calculations of the breakdown voltage and the electric field of irregular fields were clarified in the research using non uniform electrodes (needle to plane) for different distances (in mm) and comparing this with Sulphur hexafluoride and air. The theoretical calculations obtained were compared with the practical results and there was a clear match indicated. Freon (R-12) is one of the famous known types of Freon and its name in the International Union of Research and Applied Chemistry is dichlorodifluoromethane. Its chemical shape is (CCL2F2). Freon has been used in many applications in homes, and including in the industrial field, Freon gas voltage is higher in varying electric fields in gaps of a few mm and above due to negative activation compared to positive energy. Negative stimulation reduces the field near the acute cathode, leading to a high breakdown voltage.
