Lightning transients in the control and supervision systems on the HV substation

A Case Study to Risk Assessment for Protecting Airports against Lightening

“…Lightning parameters were investigated from the middle of the last century and these parameters are usually obtained from measurement taken on high objects. The most important parameters for the purpose of designing protection systems [6] are peak value of the first stroke, maximum rate of rise (inductive effects of lightning current and dangerous sparking), flash duration and total charge in the flash, specific energy in a flash [2][3][4].…”

“…The dangerous effects of strikes to airport can include actuation of safety systems, and loss of fire protection. With the advent of digital information systems and low-voltage electronic devices in safety systems, lightning protection is becoming increasingly more important to the operations of an airport [1,2].…”

“…Appearance of the lightning flash creates an impulsive fast surge which could be a source of damage for "critical" structures in APs. The type of damage depends both on the position of the point of the strike relative to the AP and on its characteristic and systems involved [2]. The occurrences which are caused by lightning can threat people, critical structures, internal electrical and electronic systems due to electromagnetic effects of lightning current, so that the selection of adequate protection measures for airports has a high priority [3][4][5][6][7][8][9][10].…”
