Wind energy, as one of the renewable and clean energy sources with the most mature technology and the best conditions for large-scale development, wind power generation has brought tremendous opportunities for the harmonious development between humans and nature.
In accordance to IEC 62305 and IEC 61400-24, below should be considered when categorizing surge protection zones and selecting/installing the SPD:
1. Lightning protection zone (LPZ 0…3);
2. Relative SPD test waveshapes (8/20 μs or 10/350μs);
3. Voltage protection level
4. Voltage and standard of power supply (230/400 V; 400/690 V; TT/TN system);
5. Harmonic wave interference
In accordance to:
1. IEC 62305: Protection against Lightning
2. IEC 61312: Protection against Lightning Electromagnetic Impulse
3. IEC 61400-24: Wind turbines-Part 24: Lightning protection
4. IEC 61643-11: Low-voltage Surge Protective Devices
5. IEC 61643-21: Surge protective devices connected to telecommunications and signaling networks - Performance requirements and testing methods
