STEMMANN-TECHNIK frost® Ground Contacts Lightning Protection gearbox main shaf t main bearing The direct discharge is to avoid mechanical damages at the WPTs and to protect the power systems and control systems in the machine des are equipped with receptors which conduct the lightning current to the hub. From there, the current is conducted to the tower structure and Since 2004, STEMMANN-TECHNIK is engaged in the development and production of lightning protection systems for wind power turbines. Here, we concentrate on the external lightning protection of the WPT as well as on discharging...

frost® Ground Contacts ENGLISH DEUTSCH Main Shaft Lightning Device Lightning Device Pitch Adjustment Azimuth Adjustment Lightning Device Lightning Device Critical points of the general construction are: B Rotor blade adjustment (pitch-adjustment) with bearing and a rotation angle of approx. 90°. Here, the lightning current is for instance fed into the main shaft or a separate current path towards the machine house / tower used respectively. The slow rotating main shaft. The lightning current is discharged via a rotating movement into the tower construction. Machine house bearing with the...

STEMMANN-TECHNIK frost® Ground Contacts frost® Ground Contacts STEMMANN-TECHNIK has developed components for the protection against lightening which transmit the discharge energy through continuous contact and which are also able to discharge the lightning current. The concept for the protections against lightning of a WPT should be devised in agreement with the manufacturer by a specialist, making sure that the requirements of current standard regulations are met and the state of the art technology, the most recent knowledge about lightning physics and electromagnetic compatibility are...
