Proposed Friction Damper for Galloping Conductor Waves

The standing wave effects of galloping conductor motion are analyzed in terms of parameters which may be evaluated in accordance with traditional procedures for dealing with analogous steady-state and transient phenomena in elementary electrical circuits. These parameters are defined and used to determine the conditions which must be satisfied to assure very completely damped galloping conductor motion. Means are proposed for incorporating the required friction resistance in a practical damper. An illustrative application is described, along with an appraisal which suggests that it may be possible to achieve sufficient control without requiring more than one of these dampers per conductor mile of overhead transmission circuit.
