摘要

Transient response plays a key role in the evaluation of the performance of grounding systems and for the protection of electrical installations under lightning strikes. The frequency spectrum of the lightning impulse contains harmonics components up to the megahertz range. The measured transient response of grounding systems under test may be distorted by spurious high frequency interference in the acquired signals, which presents challenges for the accurate analysis of high frequency performance of such systems. In this paper, the high frequency performance of a rod electrode is investigated based on measurements of its transient response under impulse energisation. A practical method is implemented to eliminate the high frequency noise in the measured voltage and current shapes, which allows a frequency domain analysis based Fast Fourier Transforms.
