Säntis Lightning Research Facility Instrumentation

The Säntis Tower was instrumented in May 2010 to measure currents of lightning discharges striking the tower. Since then the system has been recurrently updated and expanded. Currently, data associated with lightning strikes to the tower are collected at five different sites. The facility is equipped with a current measurement system, three electric field antennas, an electrostatic field mill, two x-rays sensors, a high-speed camera and four full HD cameras. This paper presents the latest measurement configuration at the facility.
