Abstract
Oppfinnelsen angår en strømsensor for å overvåke elektriske forstyrrelser på en elektrisk krets med en elektrisk leder. Strømsensoren innbefatter en magnetflukssensor for å avføle en magnetisk fluks fremstilt av en strøm som flyter i den elektriske lederen og for å tilveiebringe et signal som er representativt for strømmen, og en prosessor for å fange signalet flia magnetflukssensoren, for å detektere en elektrisk forstyrrelse på strømmen og for å tilveiebringe elektroforstyrrelsesdata. Strømsensoren kan også innbefatte en ringformet magnetisk struktur for å motta den elektriske lederen og en åpning i den ringformede magnetiske struktur for å motta magnetflukssensoren. Magnetflukssensoren er innrettet for å avføle en magnetisk fluks fremstilt i den magnetiske strukturen av strømmen i den elektriske lederen.
