The invention relates to an electrical device (10) for a power security exchange between a power consumer (20) of an electrical circuit of an assembly, in particular of a vehicle, and an power source (30) of an power grid external to said assembly, comprising: an electrical line (100) connecting the power grid to said assembly, said line (100) including electrical conductors in which a first portion (100a) is suitable for being connected to said power grid such as to enable a power exchange between the power source (30) of said grid and said power consumer (20); and a second portion (100b) is suitable for implementing an equipotential connection between the electrical mass (22) of the assembly and the ground (32) of the power grid; a first measurement system (101) suitable for measuring a common mode current (i) flowing in one of the two portions (100a, 100b) of the electrical line (100) during a power exchange between the power source (30) and the consumer (20); at least one impedance (120) connected by one of the terminals thereof to the power exchange line (100a) of the electrical line or to an internal potential of the electrical circuit; an electronic component (110) connected to said first measurement system (101) measuring the common mode current, the component (110) being configured to apply, between the ground line (100b) and another terminal of the impedance (120), an electrical quantities which make it possible to reduce the common mode current flowing in the portion of the electrical line (100) which has the current that is measured by the first measurement system (101); a second measurement system (102) suitable for measuring a residual current flowing in at least the portion of the electrical line (100) which has the current that is not measured; and a control unit configured to detect a failure of the power exchange when a value obtained from the current measured by the second measurement system (102) is greater than a threshold value.
