Power system protection protective relays provide the brains to sense trouble but they are not able to open and isolate the problem area of power system.
Lecture 24 power swings and distance relaying.
System protection is the art and science of detecting problems with power system components and isolating these components.
The coordinated arrangement of relays and accessories is discussed for the following elements of power system.
Limit the extent and duration of service interruption whenever equipment failure human error or adverse natural events occur on any portion of the system minimize damage to the system components involved in the failure and prevention of human injury.
