Functional and technical features of portable voltage transf

      1. A single voltage transformer analyzer can realize the error test of the voltage transformer without the need of resonant boosting device, standard voltage transformer, load box, calibrator and other equipment, which greatly reduces the workload of the field calibration error.

      2.the test range is wide, can test the voltage level of 6kV ~ 800kV electromagnetic voltage transformer.

      3.the internal use of 0.01 standard voltage transformer, using the differential method to test the low-voltage error of the transformer, using the inter-frequency test technology, convert the nonlinear error of PT at 50Hz, and finally get the error of the transformer.
