Abstract :
THIS REPORT has been written to present the agreed upon impulse and 60-cycle flashover values for rod gaps and suspension line insulators, together with a method of making correction for variation in humidity. The laboratory work and correlation upon which these data are based was done by the subcommittee on correlation of laboratory data∗ of the joint EEINEMA committee on insulation co-ordination. The joint committee authorized the publication in ELECTRICAL ENGINEERING of this work through a paper sponsored by the AIEE subcommittee on lightning and insulators. This makes the information more generally available to the the industry for use in connection with the general problem of insulation co-ordination.
