FIELD MEASUREMENT AND FIELD DATA PROCESSING
ON CONDUCTOR VIBRATION
(COMPARISON BETWEEN EXPERIMENTAL AND ANALYTICAL RESULTS)
(1982)Abstract
Wind-induced conductor vibrations may cause
serious damage both to the conductors themselves and
to the f~ttings.
Given the considerable importance of EHV and
UHV lines, such damage and the consequent outages
result in significant financial loss.
It is therefore fundamental that the
right choice should be made as regards damping systems
to reduce the' vibration amplitudes and to keep
stresses on conductors and fittings (spacers, dampers,
clamps, etc.) to within acceptable values. This
choice is greatly aided by predetermining the vibr~
tory behaviour of the system (conductors, spacers,
dampers) through the use of mathematical models and
computer programs.
This report describes some field tests used in
setting up the aforementioned programs.
A description is given of the methodologies em
ployed in the measurement and the subsequent processing
of data, dwelling in particular on a system
for acquiring and recording data using a minicomputer,
which enables most of the quantities recorded to be
processed on the.spot and in real time.
Lastly, the experimental resul ts obtained are
compared with those produced with the computer'programs.
