Lightning instrumentation for warning and measurement

A presentation of instrumentation techniques used at Kennedy Space Center for assessing the hazards of lightning, measure lightning currents, induced voltage effects and assess the probability of lightning strikes to launch structures. The electric field and sferics are measured to determine the lightning hazard from the clouds. Measurements are made on launch structures to determine the magnitude of lightning currents and the induced voltages. Photographs are taken to ascertain the location of lightning strikes. Data is analyzed and presented on operations personnel and the Weather Office for assessment of impact on launch critical electromechanical systems and industrial operations.
