Abstract
Integrert strømforsynings- og signaloverføringssystem som overfører ved hjelp av et par linjer kommando- signaler i fIrkantbølgeform fra en sendeenhet til en operasjonsenhet liggende i en avstand fra denne, idet signalene er sendt ved en lavspenning på omkring 36V og en frekvens over IkEz. Spenningen er stor nok til å lagre effekt i kondensatorer for å tilveiebringe strømforsyning ved operasjonspunktet uten at det er nødvendig å stoppe strømforsyningen når signalene er sendt. Systemet er spesielt egnet for sending av operasjonssignaler og motta Informasjon fra et brønnhode.
