Development of Flexible Rogowski Coil

Rogowski coil is widely applied in impulse measurement,owing to good linearity,instauration and isolation between sources and signal sides,but sometime the coil's application is limited by its metal crust.In the paper,the application of flexible Rogowski coil in impulse measurement is investigated,and the principle of outside-integral coil is introduced,then the effects of damp resistor and capacitor characteristic on coil's perform is analyzed with time-dependent,and the effects of signal line's length on measurement precise is also checked.The good perform and wide application of flexible Rogowski coil is verified through laboratory test.
