Direct Lightning Strikes to Test Power Distribution Lines—Part II: Measured and Modeled Current Division Among Multiple Arresters and Grounds The division of return stroke current among the arresters and groundings of two unenergized test distribution lines, one horizontally configured and the other vertically configured, was studied at the International Center for Lightning Research and Testing […]

Calculating the Lightning Protection System Downconductors’ Grounding Resistance at Launch Complex 39B, Kennedy Space Center A new Lightning Protection System (LPS) was designed and built at Launch Complex 398 (LC398), at the Kennedy Space Center (KSC), Florida, which consists of a catenary wire system (at a height of about 181 meters above ground level) supported

A New Comprehensive Lightning Instrumentation System for Pad 39B at the Kennedy Space Center, Florida A new comprehensive lightning instrumentation system has been designed for Launch Complex 39B at the Kennedy Space Center, Florida. This new instrumentation system includes the synchronized recording of six high-speed video cameras, currents through the nine downconductors of the new

A Kennedy Space Center Implementation of IEEE 1451 Networked Smart Sensors and Lessons Learned To meet the need for more specific and reliable information from ground support instrumentation systems and future spacecraft sensors and to support Intelligent Health Management Systems (IHMS), NASA’s Instrumentation Branch and ASRC’s Advanced Electronics and Technology Development Laboratory at Kennedy Space

Direct Lightning Strikes to Test Power Distribution Lines—Part I: Experiment and Overall Results The interaction of rocket-triggered lightning with two unenergized power distribution lines of about 800 m length was studied at the International Center for Lightning Research and Testing in Florida. A horizontally configured line was tested in 2000, and a vertically configured line

An “Anomalous” Triggered Lightning Flash in Florida An “anomalous” rocket-and-wire triggered lightning flash, a flash whose leaders do not follow the triggering wire remnants to ground, is characterized via high-speed video images at 10 and 300 kilo-frames per second, still camera images, 66–72 MHz source locations from a Lightning Mapping Array, channel-base current, and electric
