ANALISIS KEGAGALAN DAN OPTIMASI SISTEM PROTEKSI PETIR DENGAN METODE SUDUT PERLINDUNGAN DAN BOLA BERGULIR ( STUDI KASUS GEDUNG UPT-TI UNIVERSITAS JEMBER )

Abstract

Along with the rapid population growth in Indonesia that led to narrowness of the land, so development in Indonesia tend to rise, so that with the construction of the buildings on building security issues become important to note, because the buildings more vulnerable to disruption, either mechanical disruption or natural disturbances. One of the frequent natural disturbances are exposed to lightning strikes, to overcome this, you need to do is to provide better protection of buildings from outdoors or indoors or lightning protection system (SPP). Method protected corner and the ball rolling is a method that can provide external protection by placing proper finial, so that will be obtained from this method of protection right corner. From the results of the research in-house UPT-TI was still there and the tower side of the building that is not protected, it is due to improper placement of the finial and the absence finial attached to a second building, while the internal protection needs to be added to the equalizing bonding potential (IPP) on obtained pertama.serta floor safe distance between the SPP to the conductor in the building of 0.88 m.
