Measurement of lightning-induced currents in an experimental coaxial buried cable

We present in this paper experimental results obtained at the International Center for Lightning Research and Testing (ICLRT), Camp Blanding, Florida, where currents induced by triggered and natural lightning events were measured at one end of a shielded buried cable, both in the cable shield and in the inner conductor. The horizontal magnetic field was also measured. For the natural lightning events, the recorded waveforms are correlated with the data obtained by the U.S. National Lightning Detection Network (NLDN). The paper provides also a discussion of the correlation between the horizontal magnetic field and the induced current, as well as of the effect of lightning stroke position and distance from the buried cable on the induced disturbances.
