Protective relays and relaying systems detect abnormal conditions like faults in electrical circuits and automatically operate the switchgear to isolate faulty equipment from the system as quick as possible.
This limits the damage at the fault location and prevents the effects of the fault spreading into the system..
Protection devices:
System protection is the art and science of detecting problems with power system components and isolating them from the rest of the healthy system during the fault occurrence.
There are different protection devices like Fuse, Circuit Breaker (MCB, MCCB, and ACB), and Protection Relays..
Protective devices are equipment applied to electric power systems to detect abnormal and intolerable conditions and to initiate appropriate corrective actions.
These devices include lightning arresters, surge protectors, fuses, and relays with associated circuit breakers..
The objective of a protection scheme is to keep the power system stable by isolating only the components that are under fault, whilst leaving as much of the network as possible in operation.
The devices that are used to protect the power systems from faults are called protection devices..
Power system protection is a branch of electrical power engineering that deals with the protection of electrical power systems from faults through the disconnection of faulted parts from the rest of the electrical network..
Power system protection is a branch of electrical power engineering that deals with the protection of electrical power systems from faults through the disconnection of faulted parts from the rest of the electrical network..
Protection coordination is also handled through dividing the power system into protective zones.
If a fault were to occur in a given zone, necessary actions will be executed to isolate that zone from the entire system. Zone definitions account for generators, buses, transformers, transmission and distribution lines, and motors.
Advanced concepts and schemes used in power system protection including:
Power system protection is a branch of electrical power engineering that deals with the protection of electrical power systems from faults [citation needed] through the disconnection of faulted parts from the rest of the electrical network.
It’s through such a system that homes and industries in a region receive power.
Protection schemes have to be devised for these power systems, so that damage to life and property is reduced to a minimum in case of any dangerous, unforeseen circumstances.
