| Abstract: | The error of potential transformer (PT) with two and above secondary load windings is dealt with in this paper. The error computing formulas for the measuring winding of practically loaded PT are derived, based on which the measurement and calculation means for actual burden error are presented. Results of actual measurement show the validity of the proposed method. |
