ABSTRACT:
A current detection device has an annular dielectric substrate with a thin (e.g., less than one skin depth at maximum frequency) resistive foil laid down on the substrate outer surface and extending completely thereabout. Annular metal rims are affixed to the substrate edges respectively contacting the metal foil or film. A conductive strip of appropriate dimensions is received onto the outer edges of the metal rims and extends about the complete circumference of the rims. A resistive material is used to secure the conductive strip to the edges of the rims so that the entire resistance of the strip and resistance material exceeds that of the sensing metal foil to prevent shorting out of the foil.
