External Lightning Protection System for Main Office Building in the Area with High Lightning Density

In every industry which has main office equipped with a lot of vulnerable equipments that has to be protected against any risk of damages from natural causes and others. One of the possibilities of this risk is coming from weather phenomenon which we called lightning. The number of lightning strikes per square kilometer per year is very high in the area of Subang, west Java, Indonesia. Damages of electronics equipment and the death of human life have been reported. The aim of the research is to evaluate the local lightning activity and to design and install the protection system against the danger of lightning strikes. Lightning Protection System (LPS) is needed to prevent the damages, fire, and death of human life from direct lightning strikes. The main office in this area has unique structure. Due to its unique form of the building some modification is needed for the external protection by implementing the iron plate on the location of the structure which will be hit by lightning. Lightning protection system for the whole area of main office building are analysed by using the electro geometric concept to determine the lightning protection system for the mobilization of the workers and vehicles during their activities in the region which has high lightning activity.
