Abstract
The invention relates to a device for measuring an electrical quantity of one phase of an AC electric current in an overhead electrical network, comprising: a sensor designed to be attached to an electric line of the network, the sensor including: an electrically conductive plate; an electrical conductor, designed to electrically connect the plate to the line, in order to circulate a first current from the line through the conductor; a processing unit, designed to determine the electrical quantity from value values of the first electric current and a value of a capacitance between the plate and ground. The device also comprises a generator, electrically connected to the conductor and designed to inject a second current through the conductor, the second current having a frequency other than the frequency of the first current, the processing unit also being designed to calculate the capacitance between the plate and ground as a function of the second current.
