Abstract :
The practical implementation of traveling wave fault location depends on the transducer characteristics at high frequency transients as a result of faults and other disturbances In this paper, an experimental study of the current transformer parameters at high frequencies has been carried out. Transfer function has been investigated and calculated. CT parameters have been measured using different methods. The frequency response of the CT has been calculated over a wide range of frequency.
