<p>The objective of the present invention is to provide a power shield, comprising: a sensing signal line (10) which is installed on a current flow circuit to transmit a signal; and a shield cable (20) which is mounted in a peripheral location of the sensing signal line (10) and includes a noise shielding unit (22) to block a noise by generating a magnetic field when a constant current is supplied. According to the present invention, provided is the novel power shield to block an external noise by supplying the constant current to a shield terminal of the shield cable (20) to block a noise of a target signal so that a certain magnetic field can be maintained.</p> |
