Lightning Registration System Captures Lightning Data on Wind TurbinesERICO offers a lightning registration system for use on land and offshore wind turbines that are currently in operation. 
As part of a complete line of lightning protection and grounding products, ERICO offers a lightning registration system for use on land and offshore wind turbines that are currently in operation. Part of the ERITECH® line of facility electrical protection products, this system consists of three components:
• Lightning card including card holder
• Card reader (connects to a computer via USB port)
• Report-generating and registration software
The lightning cards have been tested to work in temperatures from -30ºC to +80ºC and can record strikes from 6 - 300 kA. Each card is individually numbered to tie the data to the card location or installation time. The cards are calibrated to measure current in a 10 mm circular conductor. A correction factor may be added for card reading to account for alternative conductor geometries/dimensions.
When lightning current is conducted to ground via the lightning downconductor, a magnetic field is created around the conductor. By applying a card with a special magnetic code trail perpendicular on the conductor, the magnetic field generated by the lightning will delete the data in the area where its strength is higher than the resistance of the code trail against deleting. The maximum lightning current to which a card has been exposed can then be read by a special card reader.
Recorded data can be compared to meteorological data for lightning in the area in question so that a connection between lightning impacts and breakdowns can be revealed. ERICO can provide support contacts if data analysis assistance is needed.
