发明名称 ELECTRIC FIELD AND MAGNETIC FIELD SENSOR
摘要 <p><P>PROBLEM TO BE SOLVED: To provide an electric field and magnetic field sensor in which voltage and current can be measured by one sensor in non-contact with a power transmission and distribution line and the like and which can detect a magnetic field of a high frequency wave without being influenced by an electric field terminal provided at an outer peripheral side and whose measured voltage value compensates electric field detection change by rain water. <P>SOLUTION: With a magnetic field detection coil 21 mounted in a case 22 and a plurality of conductive bodies 25 in a wire shape provided with a predetermined clearance at outer peripheral of the case 22 in a exposing manner, magnetic flux is not shielded as it runs through a clearance provided between the plurality of conductive bodies on an outer peripheral side and high frequency magnetic field is detected by the mounted magnetic field detection coil 21 and magnetic field detection intensity does not change as magnetic field detection takes precedence of water film. <P>COPYRIGHT: (C)2004,JPO</p>
