Özet

Electrostatic charging can occur by the accumulation of charge carriers on dielectric surfaces due to electrical discharges. The charges accumulated on dielectric materials in an electrical discharge device change the potential distribution, so that the electric strength of the device can be decreased. Some areas inside of the electrical discharge devices are electrically charged during the discharge, even after switch-off, charges remain for a significant time on the dielectric surface. At a new attempt to ignite the discharge, it is seen that the value of the breakdown voltage is dramatically modified. The influence of the charge accumulation on the dielectric surfaces was investigated using a discharge device that allows dielectric surface polarization. The breakdown voltage values as a sensitive measurement of the accumulated charges on the dielectric walls of the discharge device were measured.
