Today, wind generator installations gain popularity as one of the most affordable and simple methods of autonomous electrification of facilities.
Wind turbines are usually installed in open areas at high altitude, in the result of what, they are particularly exposed to lightning impact. To ensure safe and reliable operation, they must be appropriately protected against overvoltage. We offer you a special offer for the protection of wind turbines.
In the functional scheme of wind power there are the following elements and circuits that require overvoltage protection:
- the main power supply;
- communication lines;
- switchboard and control cabinet;
- converter;
- generator;
- power control, measurement and automation system;
- signal lighting and weather sensors;
Generator protection
Electrical connection between the generator of wind turbines and the transformer station is most often performed by a line of voltage of 400/690 V with TN or IT grounding system. For such voltages, we offer specially designed SPDs. PowerPro BC TNC 50-440 / 690 represent surge arresters of Class 1+2, with high resistance to lightning currents (150 kA 10/350 ms). They provide a limit voltage in the main power circuit to the level of 2.5 kV.
LEUTRON also developed a proposal to provide generator protection of level II: EnerPro CST 440 (TN system) and EnerPro EC 750 FM TNC (IT-system).
