Abstract:

Formation of microdischarges in porous dielectric materials generated by dc high voltage hasbeen investigated. Two geometrical configurations (sandwich type and corona type) and several materialswith different pore size and thickness have been tested. The I–V characteristics and currentpulse characteristics have been recorded and supplemented with the photographs of the discharge.Stable microdischarges have been successfully generated only using materials with a certain poresize and in the limited range of the I–V characteristics.
