Abstract

Abstract: The electric fields of several resistance dividers－the substitute devices of electromagnetic voltage inductor （PT）－were analyzed and calculated to determine the structural parameters of the divider．In the cal -culation of the electric fieldthe Finite Element Method of simple syntonization field （sin field） was usedand the voltage distribution of each point in the field in the form of complex number was obtained．By comparing the amplitude errorsphase-angle errors and the maximum electric field strength of the pointsthe best scheme for resistance divider design was optimized and the corresponding amplitude error -frequency characteristic was ana-
lyzed．Finally the correctness of divider design and field calculation was validated using electric circuit．

Key words: resistance divider, electric field, structural parameter, error
