Abstract:
In this thesis a new method to determine the accuracy of CVT in measuring harmonics has been proposed. Capacitive voltage transformers are known as an important tool in measuring the harmonics. However, the frequency response of CVT contains cut-off and pass characteristics, because of the resonances of the internal elements. One of the main problems is in determining the frequency response of HV voltage source capable of accurate change to apply to CVT. The proposed method reduces the voltage level of the HV source. Also, the source structure and the effect of the additional elements are described and the accuracy of the method has been evaluated by simulation and experimental results
