The clamp has a microcontroller (30) utilized to extract amplitude (E) of a reference voltage, amplitude (i-B) of earth current, and a dephasing relation (pie) between the reference voltage and a loop current. Impedance (Zb) of the earth current is calculated at a specific frequency. The microcontroller is allowed to the extract the amplitude of the reference voltage by utilizing the specific frequency and a specific contact voltage. The microcontroller is utilized to multiply the impedance of the ground by the amplitude of the reference voltage. |
