17 FT702LT Flat Front Wind Sensor Manual
Figure 12 below shows examples of lightning interceptors* and how they can be used to create a protection
zone around the sensor. It is recommended that the interceptor is made from hot dipped galvanised steel or
aluminium in order to prevent corrosion. This will ensure a long-term low impedance connection to ground.

*The standards for Lightning Protection of Wind Turbines are described in IEC 61400-24. The installation
instructions in this manual should be sufficient to ensure that the lightning protection zone around the sensor will
achieve a lightning protection level of LPZ0B as described in the standard.
