Protective apparatus for lightning and static strains

There seems to be a diversity of opinion in the operation of transmission systems regarding lightning effects A committee of the National Electric Light Association made a report to the association last year regarding the operation of protective devices. The committee has been continued and will make another report this year. This indicates that electric service is interrupted by lightning, and a desire for improvement in protective devices. The published accounts of protective devices usually contain little regarding actual operating results. Each account is generally a description of the arrester and the principle of operation as regards extinguishing the dynamic arc which follows the lightning discharge. Information that would be of great value to operating engineers is the result secured from arresters in actual service. But little has been published in this regard.
