Abstract
Flerfrekvensutstyr for å detektere elektrodetilstanden, for å oppnå reelle verdier om den indre situasjon i en elektrode hvor faseendringer frembringes, ved å anordne eksternt utstyr hvortil et lite elektrisk signal med liten effekt og variabel frekvens føres inn gjennom en godt ledende komponent og hvilket ved endring av frekvensen av den elektriske strøm, vil muliggjøre å finne elektrodesituasjonen ved ulike høyder, selv under de
