This guide provides general recommendations for performing maintenance work on energized power-lines. It is not intended to include all of the proven, practical methods and procedures; however, these selected comprehensive recommendations are based on sound engineering principles, engineering safety considerations, and decades of field experiences by many utilities. Included are technical explanations as required to cover: certain laboratory testing of tools and equipment; field maintenance and care of tools and equipment; work methods for the maintenance of energized lines and for persons workings in the vicinity of energized lines.

Uniform procedures are established for manual and automatic measurement of audible noise from overhead transmission lines. Their purpose is to allow valid evaluation and comparison of the audible noise performance of various overhead lines. Definitions are provided, and instruments are specified. Measurement procedures are set forth, and precautions are given. Supporting data that should accompany the measurement data are specified, and methods for presenting the latter are described.
