Lightning Over-Voltages on Amman-Aqaba 400 KV Line

Abstract

An attempt is made to evaluate the lightning over-voltage failure rate for Amman- Aqaba 400kV transmission line by studying the geographical and temporal characteristics of lightning causing the line forced outages. The line was divided into three sections based on weather and pollution conditions. It was found that the line failure rate due to lightning over-voltages is low compared to other types of line outages. The investigation shows that the pollution conditions do cause line failures more than that due to lightning or adverse weather conditions. However, it is recommended that full investigation of the pollution nature including the effects of dust storms, maximum and minimum temperatures, wind speed and rain falls should be exercised for less line outages

“…Also, the line is with two No. 7 AWG aluminum clad steel overhead earth wires [22]. The parameters and the location of the conductors on the tower are given in Table 7.…”

Superiority of Prostration as a Protection from Lightning Strike

“…Holle (NLSI, 2012) reported about 24,000 lightningstruck deaths and about 240,000 lightning-struck injuries globally every year (Al-Abdulaziz et al, 2006;Coleman, 1993;Demirkol et al, 1999;Djalel et al, 2007;Halasa et al, 2007;Khan et al, 2002;Koopman and Wilkerson, 1971;Meredith et al, 2010a;2010b;Odeh, 2009;Petersen et al, 2008;Rambo et al, 1999;Saum and Koopman, 1972;Stolzenburg and Marshall, 2008). Roach 2004 reports for National Geographic News (Dell'Amore, 2010) of more lightning victims than snow storms, hurricanes and tornadoes.…”

Inference and Implication from a Lightning Observation

“…The earth receives about 100 lightning every second and every year lightning kills more people than tornadoes and hurricanes and most of these deaths take place in open fields near or under trees or around water. Holle (NLSI, 2012) reported about 24,000 lightning-struck deaths and about 240,000 lightning-struck injuries globally every year (Al-Abdulaziz et al, 2006; Coleman, 1993;Demirkol et al, 1999;Djalel et al, 2007;Halasa et al, 2007;Khan et al, 2002;Koopman and Wilkerson, 1971;Meredith et al, 2010a;2010b; Odeh, 2009;Petersen et al, 2008;Rambo et al, 1999;Saum and Koopman, 1972;Stolzenburg and Marshall, 2008).
