Method and device for testing the effectiveness of a lighting ground system
First Claim
1. Method for verifying the effectiveness at a given measurement location of a lightning ground system including at least one pick-up member connected to a ground conductor, comprising the steps of:
- feeding a current to at least one pick-up member by means of an injector device,measuring the magnetic field generated by said ground conductor at said measurement location using a detector device generating a measurement signal the amplitude of which is representative of said magnetic field,comparing the amplitude of said measurement signal with a reference threshold corresponding to the amplitude of the measurement signal at a reference location a known distance d from said ground conductor and in the field of protection of the lightning ground system in order to deduce therefrom, if the amplitude of said measurement signal is greater than the reference threshold, that said measurement location is in the field of protection of the lightning ground system.

Abstract
The invention concerns a method for verifying the effectiveness at a given measurement location of a lightning ground system including at least one pick-up member connected to a ground conductor. The method includes the steps of feeding a current to at least one pick-up member by means of an injector device, measuring the magnetic field generated by the ground conductor at the measurement location using a detector device generating a measurement signal the amplitude of which is representative of the magnetic field, and comparing the amplitude of the measurement signal with a reference threshold corresponding to the amplitude of the measurement signal at a reference location a known distance from the ground conductor and in the field of protection of the lightning ground system in order to deduce therefrom, if the amplitude of the measurement signal is greater than the reference threshold, that the measurement location is in the field of protection of the lightning ground system.
