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 Säntis 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.

► Characteristics of a system to measure lightning currents on the Säntis Tower in Switzerland.
► Configuration and characteristics of the measurement system (bandwidth and accuracy).
► Samples of experimental lightning current waveforms measured by the system.
► Measured waveforms associated with negative and positive flashes were presented and discussed.
