ROGOWSKI COIL, ROGOWSKI COIL PRODUCTION METHOD, AND CURRENT MEASURING DEVICE

摘要

PPROBLEM TO BE SOLVED: To allow each position of a start end and a finish end of a Rogowski coil to agree with each other; to shorten the distance between both parts; and to thereby acquire the Rogowski coil having a uniform quality. PSOLUTION: Winding 2 and a rewinding wire 3 of the start end and the finish end of the Rogowski coil 1 and a connection wire 7 are soldered on a printed board 10, and thereby the start end and the finish end of the Rogowski coil 1 are placed easily on the same position, to thereby uniformize the quality of the Rogowski coil 1. Furthermore, cost reduction of the Rogowski coil 1 is realized by using an insulating cable for a core 6 and the rewinding wire 3. PCOPYRIGHT: (C)2007,JPO&INPIT
