<p><P>PROBLEM TO BE SOLVED: To provide a sensor for a current voltage measurement which can detect high-frequency currents. <P>SOLUTION: A sensor 1 for current voltage measurement includes a light-emitting element 13, which is connectable electrically to a current flow path where the current flows through an object to be measured; a CdS light sensor 12, which is connectable to a device for measurement electrically, and a case 11 which is constituted of a light-shielding material. Furthermore, the light emitting element 13 and CdS light sensor 12 are sealed inside the case 11. The light-emitting element 13 emits a light by the current, the CdS light sensor 12 changes its resistance value, according to intensity of the current through receiving of the light by CdS light sensor. The current value, or the like, is measured by measuring the resistance value by using the device for measurement. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
