Abstract:
A combined measurement device for measuring current and/or voltage of an electrical conductor, comprising a supporting body, a current sensor housed inside the supporting body, and a voltage sensor located at least partially inside the supporting body. A shielding is positioned around the current sensor. The current sensor and the voltage sensor are mutually arranged so as the shielding shields at least partially both the current sensor and the voltage sensor against external electric field disturbances.
