Voltage dependence measurement of a 110 kV LVE-TSVT

The paper presents the development of a 35 kV fully-insulated two-stage voltage transformer(TSVT), and its applications by connecting in series with another 35 kV semi-insulated TSVT to determine the voltage dependence(VD) of a 110 kV TSVT. The result showed the VD of the 110 kV TSVT is around −1.6×10 −6 and +1.6 μrad in magnitude and phase, respectively.
