Abstract

Det er beskrevet et nedihulls signalmottagende system hvor et par oppspenningsanordninger (51) brukes for å skape elektrisk forbindelse med en nedihullsstruktur, og som er forbundet med hverandre via en masseleder (52). Signaler trekkes ut ved hjelp av en påvisende anordning (53) som ikke avbryter ledningsveien. Verktøyet gir en ledningsvei med lav impedans, som signaler fra den omgivende struktur kan flyte langs for å muliggjøre påvisning.
