Excerpt from Final Report of the Joint Committee on Inductive Interference to the Railroad Commission of the State of California: Presenting the Results of an Investigation of Inductive Interference by Power Circuits With Communication Circuits and Including Rules Recommended for the Prevention or Reduction of Such Interference A previous report by this Committee to 'the Railroad Commission was rendered on July 7, 1914, embodying the results of the first two years of the investigation and including provisional rules for the prevention or mitigation of inductive interference, based on the information available at that time. The rules therein recommended were adopted by the Railroad Commission in its General Order No. 39, effective August 20, 1914. The previous report also contains an outline of further investigations which this Committee considered essential in order that additional information might be acquired for amplifying and revising the rules to make them more definite and complete. These further investigations have now been carried out. As far as practicable, and certain additional work directed toward the same end has also been done.
