FAQ

What should be considered when selecting SPDs for wind turbines?

Key factors include lightning exposure, system voltage, installation location, discharge current capacity, vibration resistance, temperature range, grounding system, and coordination between different protection levels.

What types of SPDs are used in wind power systems?

Wind power systems may use AC Power SPDs, DC Power SPDs, Signal & Data SPDs, and communication line SPDs. The exact selection depends on the turbine electrical architecture and protection zones.

Where are SPDs installed in a wind turbine system?

SPDs are commonly installed in the nacelle control cabinet, tower base cabinet, converter system, pitch control system, power distribution cabinet, communication system, and transformer-side distribution panel.

Why do wind power systems need surge protection?

Wind turbines are tall structures installed in open areas, which makes them highly exposed to lightning strikes. Surge protection is necessary to reduce damage to generators, converters, control systems, sensors, and communication equipment.

What is a Wind Power SPD?

A Wind Power SPD is a surge protective device designed for wind turbine systems. It protects electrical equipment inside the nacelle, tower, control cabinet, converter cabinet, transformer, and communication system from lightning surge damage.
