PARTIAL DISCHARGE MEASUREMENTS ON BÖNING MODEL

Igor Kršňák

   Well-known abc circuit, Gemant-Phillipow three capacitors model, however proved for industrial purposes, is a too simplified representation of the actual behaviour of the dielectric. This can be better described with the aid of Böning model considering during the discharge processes also the charge movement along the surface of cavities. A laboratory model of this type has been constructed and both voltage across the cavity and number of discharges were measured and compared with the theoretical assumptions.

Keywords: apparent charge, Böning model, ignition voltage, partial discharge, remanent voltage, return voltage
