Abstract

A  modelization  of  a  toroidal  current  sensor  with  air  gaps  using  the  3D  finite  element  method  is  presented.  The  errors  associated  with  this  sensor  have  been  evaluated  and  the  experimental verification has been carried out.With  this  model  we  try  to  study  the  sensitivity  to  the  crosstalk  error  of  this  kind  of  current  sensors  in  function  of  two  design  parameters,  the  width  of  the  air  gap  and  the  position  of  the  sensor with respect to the cable carrying current.
