Testing and Modelling of Voltage Transformer for High Order Harmonic Measurement
Harmonics have become an important concern in todays power system network.Conventional Inductive Voltage Transformers (IVT) are used as the essential instrument for harmonic measurement.However,the frequency bandwidths of the IVTs are limited.As a result,they are not suitable for high order harmonic measurement.This paper thus presents the testing and modelling of the frequency response of a 33kV single phase IVT up to 5 kHz.The test system setup for testing the IVT frequency response is described.The frequency response of a 33kV single phase IVT is measured and analyzed.A model of the 33kV IVT is developed and validated by comparing the simulation with the experimental results.Good correlation between the two results is observed.The impact of burden on the frequency response of the 33kV IVT is also simulated and discussed.
