Transformation of Transient Overvoltages by Inductive Voltage Transformers [PDF]
Sensors, 2021 Overvoltage transients occur after any type of switching activity in a power network, such as breaker operation, fault occurrence/clearance and rapid load change. This distortion of voltage is transformed to the secondary circuit of a voltage transformer.

Development of ultrahigh‐voltage standard voltage transformer based on series voltage transformer structure [PDF]
IET Science, Measurement & Technology, 2019 An ultrahigh‐voltage standard voltage transformer (VT) based on series voltage transformer (SVT) structure is described. A precise isolation VT is designed to realise the connection between the VTs of an SVT. Moreover, the ratio and errors of the SVT are discussed and calculated to reduce the magnetic error of the isolation VT, and
