ABSTRACT
This chapter discusses facility grounding with an eye toward lightning protection and safety of personnel. One aspect of lightning protection that is frequently overlooked is the ferrite toroid. A toroid is a ring of compressed carbon and ferrous material that is often used as a core for winding transformers. Ferrite toroids should be installed on any cable connected to a device that could be damaged by lightning energy, including coaxial and power cables, as well as audio cables, remote control wiring and telephone or data lines. Station ground is quite simply the lightning protection ground, consisting of ground rods and conductors bonding the tower to the building and the contents inside. Electrical ground is for overcurrent protection and safety of personnel and equipment. Surge protectors come in many shapes and sizes, some better than others. The two most common surge protector devices encountered contain either metal oxide varistors or silicon avalanche suppression diodes as the protection devices.
