Tests of the 'early streamer emission'principle for protection against lightning
NL Allen, KJ Cornick, DC Faircloth, CM Kouzis - IEE Proceedings-Science …, 1998 - IET
Experiments are described which are designed to test two devices based on the 'early
streamer emission'(ESE) principle, for lightning protection, against the traditional Franklin
rod. In all three cases, the device was subjected to a steady negative electric field from a
sphere, simulating the field beneath a thundercloud, prior to application of a superimposed
negative impulse field, simulating the field due to the downward leader. The first device
consisted of a vertical rod to which a subsidiary 1/50 µs positive impulse voltage, variable up …
