A study on the early streamer emission (ESE) lightning protection system

Early Streamer Emission (ESE) Lightning Protection (LP) system is a relatively new approach in solving the perennial problem of lightning damage, which has been associated with the use of Franklin Rod (FR). Based on theoretical consideration and some previous work by several researchers, the ESE is...

Electronics Nuclear engineering Early Streamer Emission (ESE) Lightning Protection (LP) system is a relatively new approach in solving the perennial problem of lightning damage, which has been associated with the use of Franklin Rod (FR). Based on theoretical consideration and some previous work by several researchers, the ESE is believed to be providing more effective protection against lightning than would a FR system.

Visits to several sites, which employ these systems, have enabled physical observation of the after effects of lightning be recorded for analyses. The results show that slightly rounded air terminal, which is typical of ESE system offer better interception ability than that of sharp terminals, which is the typical FR design.

This conclusion is substantiated by field observation obtained from the installed systems where the ESE system has been found to intercept more lightning strikes than that by the FR. 2004-10 Thesis http://eprints.utm.my/id/eprint/5774/ http://eprints.utm.my/id/eprint/5774/1/NguEngEngMFKE2004.pdf application/pdf en public http://dms.library.utm.my:8080/vital/access/manager/Repository/vital:62111 masters Universiti Teknologi Malaysia, Faculty of Electrical Engineering Faculty of Electrical Engineering
