Wind energy is produced by the flow of air which is a form of conversion of solar energy. The total reserves of wind energy resources are very large. The wind power industry is currently developing rapidly in many countries such as America, Germany, India, Spain, Britain, Canada, France, Italy, Brazil and etc. It plays an important role in optimizing energy structure and promoting energy conservation and emission reduction.

Why Wind Turbine Engineers Use Inclinometers on Wind Turbines?
All the wind power farms are built in wind-rich districts where the climatic conditions are harsh. The wind towers are subjected to irregular and variable-speed wind, and the gear box and blades are easily to get damaged or break down, bringing about economic losses and causalities. Additionally, the natural disasters such as earthquake, landslides and etc. may affect the safe and stable operation of the wind turbines.
According to the report of Power Technology, about 737 incidents were reported from the Britain offshore windfarms in 2016. The report shows that increasing wind turbines are constructed and increasing wind turbine accidents occur: about 220 wind turbine accidents from 1999 to 2003, 470 wind turbine accidents from 2004 to 2008, 765 accidents from 2009 to 2013, and 845 accidents from 2014 to 2018.
According to the above data, it can be seen that there were more and more wind turbine accidents year by year.

Successful Application of SST400 and SST810 Inclinometer in Wind Turbine Health Monitoring in China
In order to avoid the tilting of wind turbines, affecting the normal operation and safety of wind towers, it is of high necessity to monitor the verticality of the wind turbines by using the inclinometers. When the tilt of wind tower exceeds the safe value, the early warning can be sent out and the operation personnel can carry out necessary inspections and maintenance at once.
In 2018, Vigor Technology SST400 static inclinometer and SST810 dynamic inclinometer have been successfully applied in wind turbine health monitoring in China. The partner is a state-level high-tech enterprise dedicated to improving the health of industrial equipment and promoting the transformation of industrial maintenance systems. It is professional in industrial equipment online monitoring, intelligent diagnosis, cloud services and etc.

Currently, the customer has purchased 115 sets of high-accuracy SST460 inclinometers and 100 sets of high-performance SST810 dynamic inclinometers for intelligent monitoring of wind turbines in Zhejiang and Hunan Province of China. The SST810 dynamic inclinometer is installed on the top of tower for monitoring the roll angle and pitch angle of the wind turbines. The SST460 tilt angle sensor is installed on the tower base to monitor the verticality of tower body. According to the customer feedback, the inclinometers are working well with stable data output and real-time dynamic monitoring performance.
