The Lightning Interception Blade Implant is tested according to the existing IEC 61400-24 Ed1.0, as well as the IEC 61400-24 Ed2.0 (CD) - even with extended test requirements for Japanese Winter Lightning with specific energies up to 20MJ/Ohm.
The high voltage strike attachment test determines the likely strike points on the blade LPS, where 54 flashovers from the blade to the opposing ground electrode is applied. All flashovers must be intercepted on the intended air termination to pass the test.
The LIBI has been tested as a single component without being implemented in an actual blade, and as part of the blade adaptions completed so far where the LIBI is installed in real blade shells.
In either case, the LIBI passed the Initial Leader Attachment test without any failures.
The subsequent stroke test was previously known as the swept channel test, and is conducted to ensure that subsequent current strokes flowing in the swept channel after the initial attachment does not result in punctures of the blade.
Again the LIBI has been tested alone and being implemented in the blade shells for the various adaptions, and in any case the system proved successful.
The conducted current test injects realistic lightning current pulses into the lightning connection components, and thereby verifies the capability of withstanding the electro dynamic effects of the lightning current.
The different parts of the LIBI from the immediate solid metal tip to the down conductor cable have all been tested up to LPL1, showing compliance with the most severe lightning environment
The arc entry test exposes the metal surfaces of the air terminations to the erosion occurring from the charge transfer during direct lightning attachment. Different material combinations have been tested successfully, to include the material performance in the individual design adaption, and to be able to tailor maintenance and inspection intervals as required by IEC 61400-24 Ed2.0 (CD).
