Influence of span length and impulse front time on earthing measurement accuracy of power line towers

The article discusses the issue of measuring and assessing the features of power line tower earthings using fast-changing waveform. The study analyses the effect of impulse front time and the line span length on errors made during these measurements using impulse meters. It has been found that the assessment conditions similar to the static measurement results occur for the use of 4 μs current impulses and such procedure is useful for evaluating power line tower earthings.
