Transformer structure is modeled by simulation software to emulate the propagation characteristic of EM wave emitted by PD in transformers.The effect of transformer core and tank gap on signal propagation is discussed.The results show that EM wave propagation is attenuated by core and gap
and the maximal value of EM wave is appeared in the corner of transformers.The detection result will be preferable if transducer is fixed at these positions.
