Field Trials of Galloping Control Devices for Bundled Conductor Lines
|
|
The main objective of this project is to evaluate the performance of promising add-on
devices to control galloping due to ice and wind on bundle conductor transmission lines.
To accomplish this objective, a survey of Canadian electrical utilities was conducted during
1984 to determine the extent and severity of bundle line galloping across Canada. Based on
the results of this survey, field test sites on 2,3 and 4 conductor bundle lines were selected
from most of the provinces. Two types of galloping control devices, detuning pendulums
and interphase spacers, were purchased or built and then installed at the test sites.
Observer crews from the local utilities were assigned, and trained, initially and in annual
refresher training courses, to take systematic records of galloping occurrences at their
respective sites.
