摘要
To corroborate the induced voltage suppressing effect of an overhead ground wire, lightning induced voltage and grounding wire current measurements were conducted. The distribution line and the instrumentation used in the experiment are described and observation results and theoretical examination are presented. Observation results of grounding wire current were compared with the calculated results, which are given using the suppressed voltage of the phase conductor on the same pole, and are found in comparatively good agreement with each other.
