Abstract

The device has a shielding housing (1a) internally provided with a C-shaped ferrite magnetic core (2a) that is wound with a coil (5a). Another shielding housing is internally provided with another C-shaped ferrite magnetic core (2b) that is wound with another coil (5b), an integrated circuit (3) and a voltage divider (4). An input end of the integrated circuit and the latter shielding housing are connected with the latter coil. An output end of the integrated circuit is connected with the voltage divider. An output end (12) of the voltage divider outputs a measurement signal.
