Calculate the breakdown voltage, breakdown field strength and Townsend's first ionization coefficient of an air-insulated electrode system having an electrode spacing of a = 3.0 cm at T= 273 °K and p = 760 Torr (A(T = 273 °K) = 24.4 1/cm.Torr , B(T = 273 °K) = 341.6 V/cm.Torr, y = 1/5000). b) What can you say about the accuracy of the calculations, why? c) Calculate the critical pressure and corresponding breakdown voltage and breakdown field. d) Calculate the discharge voltages at a high pressure (4 atmosphere) and a very low pressure, (0.2 Torr). If you were to design a high voltage insulation system, what would be your choice: Normal pressure (760 Torr), high pressure (4 atmosphere) or very low pressure (0.2 Torr), why?
