Abstract

The present work describes an experimental study of corona characteristics performed on single conductors under different parameters. The actual different modes of corona were analyzed as they appear in wire to plane configuration for wire diameter ranging from 0,3 to 2mm and for gap lengthes up to 8 cm. Measurements are made to show the effect of circuit resistance on critical corona voltages of thin wires. The circuit resistance is varied from 5 to 15m ohm. For positive corona it is observed, that the circuit resistance makes burst pulse or onset streamer appear t the same time with glow corona. On the other hand the steel, copper and aluminium materials are used-as an example-showing the effect of different material on several corona modes, under A.C voltage and D.C. voltage of both polarities. Critical corona voltages are greatly affected by weather conditions and tend to decrease as the relative humidity increases and the decreasing in critical corona voltage is more higher in the case of moistened pollution conditions.
