| Abstract: | The Rogowski coil with a nonmagnetic core, which is adaptable to on line monitor partial discharge in power transformer,has been studied.The equivalent curcuit that take account of the effect of transmission line has been given.Based on this equivalent curcuit it has been analysed and calculated that the various parameters of current transducer affect on the frequency characteristic and present the design method of Rogowski coil with a nonmagnetic core. |
