“…Some researchers have recently reported lightning parameters using high speed video observations [21]. The lightning parameters may be measured using Rogowski coils and shunt resistance techniques [22]. The correlation between the lightning current and luminosity does not remain unchanged during a flash even for a pulse.…”

Lightning is one of the fascinating phenomena exhibiting tremendous natural power. It is source of awe, curiosity, enticement, inspiration as well as fear. On average, 50 lightning strikes occur on earth in one second. Fortunately not all of them kill people, albeit 10% people fall prey to lightning annually, out of which hardly 20 to 25% die. Lightning injures victims by heat, shockwave, intense brightness, radio waves, and secondary slip or fall mechanisms. Lightning injury is different from the normal electric shock as it involves transient flashover unlike the electrical contact freeze, wherein alternating (AC) and direct currents (DC) pass through the conductive interior body. Vacuity in knowledge is the driving force behind discoveries and inventions. Lightning experts had hardly developed any concurrence on lightning physics, and the observation of dark lightning complicated the Gordian knot. Lightning preventive, alerting and control devices help reduce fatality rates by the bolts out of blue skies. Lightning was considered to be the second cause of death making natural disasters after flashfloods but preventive measures have slithered it down to the third place in developed countries. Lightning prevention rule recommends 'when the thunder roars, go indoors'. This work describes lightning characteristics, damage thresholds to humans, machines, energy infrastructures, airplanes, wind turbines, light railway tractions, underground cables and pipelines. Power and energy lifelines such as transmission lines, oil tankers and gas or petroleum pipelines are susceptible to lightning strikes. Artificial rocket and laser triggered lightning protection and control techniques help to divert the lightning attacks. Interaction of lightning with power and energy infrastructures disrupts these lifelines. However, lightning itself is viewed as an extraterrestrial energy source. Lightning energy harvesting is an interesting application which has been investigated quantitatively.

Nowadays some measuring system has been developed in order to measure directly electrical activity in tall objects likes power distribution lines, in this case, the obtained results are employed in the design of the protection systems. In the case of lightning rod installation in buildings, there are not so many collected data since there is very poor monitoring of the real time behaviour of lightning. Besides, the protection model applied for lightning rod installation is still mainly based on theoretical models data which are been revised nowadays. Moreover, the statistical data about lightning characteristics have been registered in some few points where equipment has been installed (mostly in tall structures, mountains, etc..) which may not be representative of the wide variety of different types of installations and emplacements. This paper describes the design and acquisition strategy followed to obtain an autonomous measurement micro station developed to measure some lightning parameters in a wide mesh of real lightning rods installations. Micro stations are small acquisition systems allowing measurement of electric activity in the lightning rod and electric field recording in the previous moments of the lightning stroke and some milliseconds after. The main utility of this system is the possibility to create a distributed network of sensors in several installations around a large area. Instead of triggering lightning or choosing points with high number of lightning impacts, the use of several measurement points should provide an acceptable amount of data in real installations correlated to the nature of emplacement.
