Icing Test and Measurement Site.
Newfoundland Hydro Icing Test and Measurement Site at Hawke Hills near
This site is at 300 metres above sea level near the summit of the Hawke Hills,
6 km. south of Holyrood. Its elevation, topography and lack of tree shelter
can result in very strong winds which, during freezing rain storms, can lead
to considerable ice accretion on power transmission equipment. This view,
looking towards the south, shows the test transmission line and supporting
triangular tower (centre), three recording precipitation gauges, (right
foreground), air temperature and humidity sensors in the "screen" ( white box
left of centre), passive near-surface ice accretion measurement rods (left of
tower), and wind speed and direction sensors (on the pole to right of tower).
All instrumentation is operated continuously by Newfoundland Hydro, enabling
the ice loads during freezing precipitation episodes to be related to
accompanying meteorological conditions.
