In this work, we will refer to research and methods of obtainment of the plasma in the laboratory, using current limiting method in the electrode with the special channels, environmental excitation and the types of discharges that occur in it. We created a special electrode with separated channels to prevent its destruction; also, we perfected the first coefficient Townsend for studding of the processes that occur in it. This special electrode improved the characteristics of the obtained plasma, and gives us possibility of routing plasmas parameters, also this electrode don’t need a preventive ionization of the environment included between the electrodes
