An electromagnetic voltage transformer is made up with one single-stage SF6 gas isolation transformer and one or two complex single-stage SF6 gas isolated voltage transformers in series, for super and special high voltage. The most upper transformer has one iron core, and the nether and complex single-stage SF6 gas isolated transformer have two iron cores. One iron core makes into single-stage voltage transformer, the other makes into high voltage isolated transformer and the once time winding of high voltage isolated transformer joins compensate capacitor and the once time inputting end. And its second time winding joins the second time winding of single-stage voltage transformer and the second time outputting end. It adopts series-wound method to improve the electric field distribution of super and special high voltage electromagnetic voltage transformer, overcomes the shortage of imbalance of each core flux and the influence by ground capacitance, reduce the production difficulty and cost. It uses the technology for producing gas isolated voltage transformers to make up electromagnetic voltage transformer for super and special high voltage.
