Abstract

Kommunikasjonsutstyr for nedhullsbruk og som omfatter et vektrør (101) omfatter et første parti (103) og et andre parti (105) som er innbyrdes atskilt av et elektrisk isolerende materiale (67), samt midler (22, 63, 77, 81) for å generere et elektrisk signal samt for å påtrykke det elektriske signal på vektrøret (101) slik at det elektriske signal sendes inn i en geologisk formasjon som utbores, med det særtrekk at midlene for å generere det elektriske signal omfatter en vekselstrømsgenerator (22, 63, 77, 81) samt utstyr (2, 4, 10) som reagerer på en elektrisk utgang fra vekselstrømsgeneratoren ved å regulere generatorens rotasjon.
