Fundamentals of Protective Relays
Protective relays are designed to protect zones of the power system. When applying protective relaying, the power system is divided into sections so that the protective relays provide "zones of protection.". Sometimes it is common for zones of protection to overlap so that multiple layers of protection are afforded to each piece of equipment.
