Product Details
Clearance monitoring calculates the distance between the blade and
the tower
1,Product introduction
The clearance radar transmits the ranging data or the calculated
clearance value data to the wind turbine master control, and the
wind turbine master control takes corresponding actions according
to the data, such as adjusting the pitch angle when the clearance
value is low, and emergency shutdown when the clearance value is
too low.
