A. I. E. E. specification for testing high-tension porcelain line insulators

During the last three years the subject of the inspection and test of high-tension porcelain line insulators has been under discussion by the A. I. E. E. The need of more uniformity in the commercial testing practise on such insulators has long been manifest and the very erratic behavior of insulators on several of our important lines has indicated a need for more searching tests. As a result of the consideration of these questions by various Institute committees during this period a specification has been drawn up by the present Transmission Committee which is intended to serve as a model or skeleton specification covering the inspection and testing of high-tension line insulators.
