CURRENT DETECTION SENSOR USING A ROGOWSKI COIL AND A ROGOWSKI COIL MANUFACTURING METHOD

摘要

PURPOSE: A current detection sensor using a Rogowski coil and a Rogowski coil manufacturing method are provided to improve linearity by forming an elimination coil in order to cover a sensor coil and by eliminating input current and surrounding noise.;CONSTITUTION: A plurality of insulator sheets(110,120,130,140,150,160) is laminated. Sensing coils(124,154) are formed on one or more insulator sheets. An elimination coil is formed on one or more insulator sheets and surrounds the sensing coil. A ceramic printed circuit board comprises a high temperature sintering ceramic sheet. A plurality of insulator sheets comprises a low temperature sintering ceramic sheet.;COPYRIGHT KIPO 2012
