Abstract :
In an effort to determine present operating practice relative to the installation and performance of high voltage lightning arresters on electric power systems, the A.I.E.E. subcommittee on lightning arresters and the N.E.L.A. subject committee on lightning arresters circulated a joint questionnaire on that subject to 22 companies in various parts of the United States. Data obtained in the replies to the questionnaire are summarized in this report. While it is believed somewhat premature to draw definite conclusions, nevertheless certain definite trends may be observed.
