Document issued by the Office of the Attorney General of Texas in Austin, Texas, providing an interpretation of Texas law. It provides the opinion of the Texas Attorney General, Grover Sellers, regarding a legal question submitted for clarification: Construction of certain provisions of S. B. 269, 49th Legislature, 1945.

From introduction: "This study is concerned with the shape of the electrodes of high-voltage insulator and with the method of joining them to the dielectric. The study is limited to insulators operating in vacuum, with special interest in the cases where strong magnetic fields are present. It is further limited to insulators with the high-voltage electrodes maintained at negative potential. The object of the study was to obtain information that would aid in improving the design of the insulators in two respects. First, to decrease to a minimum the number of charged particles set free which may directly or indirectly cause early failure of the insulator. Second, to increase the voltages at which partial or complete flashovers occur. Therefore, experiments were made to determine the principal phenomenon which have as their primary source the insulator under high electrical stress in vacuum."
