A system for the measurements of lightning currents at the Säntis Tower

The paper presents the characteristics of a system suitably developed to measure lightning current waveforms on the Santis Tower in Switzerland. The paper first describes the configuration of the system then presents the characteristics of the measurement equipment, in terms of bandwidth and accuracy, inferred by means of experimental tests. Finally, we present and discuss examples of waveforms measured using the system. (C) 2011 Elsevier B.V. All rights reserved.
