Overvoltage Protection (OVP) System for Wind Turbine Lights

Approved for Siemens Wind Turbines

Flash Technology’s Overvoltage Protection System (OVP) is a surge handling device rated up to 40kA 8/20µS. It is designed for in-line installation between a wind turbine light and the supply interface located in the nacelle of wind turbines. The OVP provides protection from direct and indirect effects of lightning or other surge-related damage to the host equipment.

 

Two versions of the OVP product are available:

  1. The OVP product provides protection for the AC power conductors and the beacon’s alarm dry contact conductors.
  2. The OVP-RADAR product additionally provides protection for the beacon’s radar control inputs.
