The Insensys Rotor Monitoring System (RMS) has received GL certification for the detection and measurement of ice, under both static and dynamic conditions.
Germanischer Lloyd (GL) conducted tests on a fully operational 2.4 MW turbine to assess the performance of the RMS system. Different masses were added to the turbine blades and the algorithms were tested under a variety of operational and static conditions to determine their ability to accurately measure the accretion, and loss, of ice on blades. The tests demonstrated that the system can reliably detect a 40 kg mass on a 10,000 kg blade (0.4% of blade mass), and that under most conditions the system can detect levels as low as 0.26% of rotor blade mass, despite the effects of turbulence, wind shear etc.
