Interpretation of Field Vibration Data

Field and laboratory experiments concerning overhead transmission-line vibration show correlation between conductor strain and differential displacement. A method for converting f- differential displacement to strain is described. This conversion is necessary so that data from wide-spread geographical locations may be directly comptred. It is pointed out that, while the dynamic strain is important, it must be combined with the static strains to learn the true stress environment of a given conductor. Instrumentation and data gathering procedures are described.
