Abstract

Et system for å måle en spenningsdifferensial i et strømførende rør (102) ved å justere et fremdriftsinstrument (108) for å transportere systemet i røret (102), idet systemet omfatter en første kontakt (116) for å opprettholde elektrisk kraft med røret (102) når instrumentet (108) beveges gjennom røret (102), en andre kontakt (118) anbrakt i avstand fra den første kontakt (116) for å opprettholde elektrisk kontakt med røret (102) når instrumentet (108) beveges gjennom røret (102) og en spenningsavlesningsenhet (212) forbundet til den første kontakt (116) og andre kontakt (116) for å måle spenningen mellom den første kontakt (116) og andre kontakt (118) når instrumentet beveges gjennom røret.
