Influence of Magnetic Field on Characteristics of Corona Discharge in Wire-Cylinder Electrodes Configuration

The behavior of corona discharge was investigated in wire–cylinder electrodes under the effect a crossed magnetic field. Townsend’s formula used commonly with modified empirical to evaluate different parameters positive and negative discharge. By using least-squares fitting, dimensional constants A, K, exponent n displayed significant dependence on applied An improvement pre-breakdown has been achieved by For both polarities, while field is present, breakdown voltage VB inception V0 increased, whereas current decreases. In addition, greater absence field, opposite occurred regarding Furthermore, streamer demonstrated triggering applying
