Abstract

En fremgangsmåte for romladningsmåling i en koaksialkabel som omfatter en inner- leder (2), en kabel skjerm (3) og en elektrisk isolasjon (4) mellom innerlederen og kabelskjermen, hvor kabelskjermen fjernes på begge sider av et måleområde, en elektrisk spennings- puls genereres av en elektrisk puls- generator (10) og påtrykkes over en del av kabelens isolasjon (4) innenfor måleområdet, et akustisk signal, ved nærvær av romladninger i kabelisola- sjonen, genereres av spenningspulser i samvirke med romladningene, og et eventuelt akustisk signal registreres av en lydregistrerende anordning (8). En jordet, ringformet, ytre elektrode (7) anbringes rundt måleområdet, den lydregistrerende anordning anordnes i direkte kontakt med den ringformede, ytre elektrode, og spenningspulsen påtrykkes på kabelskjermen på begge sider av måleområdet, og tilkoples via kabelens impedans til kabelens innerleder.
