Full-scale tests of torsional damper and detuner (TDD)antigalloping device

摘要

A new antigalloping device for overhead lines with bundlenconductors was introduced ten years ago, after laboratory tests andnobservations on actual 400 kV lines. A systematic full-scale test wasnperformed in Kazakhstan in order to better evaluate torsional damper andndetuner (TDD) efficiency. This report details the test station and thenresults obtained over a several month period of testing and measurement.nThe tests were carried out thanks to the mutual efforts of the ESSP andnthe Kazakh Power Research Institute (KazNIIE) at the field tests standnlocated in Chokpar
