Abstract

In order to ensure the accuracy and reliability of electric energy metering of different grids and regions to guarantee the interests of power generation

transmission and customers and to carry on the on-site calibration test of CVT error characteristics in UHV grid

the standard UHV voltage transformer（VT） integrated device has been developed. Based on the principle of power-frequency voltage addition and the design idea of using a special tank compact structure

the UHV VT integrated device is designed to be upper and lower levels of GIS units

which reduces the volume and weight of the device to accommodate the UHV transformer on-site calibration vehicle load. The tank size and material are determined by theoretical calculation. The 3D modeling and optimization of isolation transformer are designed by electromagnetic simulation software. The test results of prototype indicate that the power frequency withstand voltage of 630 kV and the accuracy of grade 0.05 of UHV VT integrated device both meet the ultra-high voltage on-site trials.
