Study of Lightning Current Magnitude Through Distribution Arresters. Final Report

摘要

This project was undertaken to determine the current magnitude of lightning surges discharged through distribution arresters, and to determine the frequency of lightning strokes through distribution arresters. In the fulfillment of these objectives, the currents were determined from arrester gap etchings caused by lightning surges. Inspection of the gaps led to the conclusion that two distinct types of etchings had been produced. These were compared to 8 x 20 mu s surges and to surges of longer duration produced by tests at the General Electric Laboratory. All arrester data were statistically analyzed and published in the from of tables and graphs. (ERA citation 05:006829)
