<p><P>PROBLEM TO BE SOLVED: To solve a problem of having difficulty in ensuring dielectric strength from a primary conductor and in carrying out high accuracy measurement due to the effect of electric field noise from the outside in a conventional current sensor configured to install the U-shape primary conductor in an insulator such as a printed board including a current detecting device. <P>SOLUTION: A sensor board including the current detecting device is configured to be installed in an insulating case having an opening and a shielding layer. The dielectric strength of the sensor board and the primary conductor is thereby ensured easily to achieve high accuracy measurement. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
