WTG Lightning Protection System Testing

The testing of the Lightning Protection System on Wind Turbines is something often overlooked and by not having a fully functioning system could result in catastrophic failure and damage, leading to expensive repairs, replacement and risk to human life.

Until recently, the only method for carrying out the WTG Lightning Protection System testing was using rope access, which can be lengthly, costly and dangerous.

By using drones and its possible to dramatically speeds up the inspection process over abseiling and deploying rope access teams from the nacelle

Traditional methods of WTG Lightning Protection System testing have utilised resistance based measurement to ascertain whether faults exist in the system.

New, patented and certified (TUV SUD) approved technology from German technology provider- TOP7 now allows full WTG Lightning Protection System Testing in a fully ‘contactless’ way, completely negating the need to touch the blade during inspection.

Further more, this advancement also allows visual inspections of blades and Lightning Protection System testing to be carried out side by side, reducing downtime and increasing data collection throughput.

The ability to identify down-conductor damage and specify its location within a 30cm area is also a huge game changer for OEM’s and O&M’s alike.

Insurance and warranty claims will also require that Lightning Protection Systems are regularly tested, as in the event of a claim, if the system did not perform due to malfunction and had not been tested at the recommended intervals, this claim could end up void,- resulting in the customer having to pay out large sums of money for repair or replacement.
