Abstract

A method for measuring a temporal drainage of an alternating current flowing through a measurement object, in which a Rogowski-Steinhaus-Chattock coil is aligned on the measurement object, at least one isolating line is inserted into coil windings of the Rogowski-Steinhaus-Chattock coil, said isolating line minimizing a capacitive coupling of the coil windings of the Rogowski-Steinhaus-Chattock coil with one another and/or with at least one further electrical line, and a voltage induced by the alternating current in at least one measuring line comprising the Rogowski-Steinhaus-Chattock coil is measured. A corresponding sensor and a method for providing a sensor of this type are furthermore disclosed.
