Cost efficiency, high yields and system safety are the most important factors in the operation of wind turbines. To ensure efficient operation of wind turbines even in the windiest winter months, accurate detection of icing is required.

Hoarfrost is a form of fog-frost deposition, usually thin, fragile ice needles or scales that adhere only loosely to objects and are formed almost exclusively by sublimation. The prerequisites for the formation of frost are high humidity (around 90 % or more), weak wind and temperature values generally below minus 8 °C.

How to ensure safety during icing conditions (especially with regard to ice fall and ice throw) – Ice accumulation on wind turbine rotor blades has a crucial impact on operation and maintenance. Lower return due to aerodynamic imbalances as well as safety of the power plant and its surroundings are of central importance.
Regardless of whether a wind turbine is located next to a highway or in the mountains where skiers and hikers pass by – It should be always ensured that service technicians and any trespasser are safe in any turbine operation mode.

Modified safety regulations of wind farm operations in France (in force since January 1, 2021)    Click here to the French version of this article On June 22, 2020 a new decree was published by the French Government, to bring some modifications in the safety regulations of wind farm operations (ICPE regulation). Before the modifications…

Minimise risks such as ice throw and increase yield with ice detection and temperature measurement directly on the rotor blade surface
