Is achieved by two main methods. – Time-grading/Current Grading. • Relays are set to operate depending on the time and current characteristics. – Unit systems. • Current is measured at several points and compared. 26. Timeliness - Speed. • Faults must be isolated as fast as possible. • Speed is necessary for two main

Power-system protection is a branch of electrical power engineering that deals with the protection of electrical power systems from faults through the isolation of faulted parts from the rest of the electrical network. The objective of a protection scheme is to keep the power system stable by isolating only the components that

System protection is the art and science of detecting problems with power system components and isolating these components. Problems on the power system include: 1. Short circuits. 2. Abnormal conditions. 3. Equipment failures. NERC defines the protection system as: Current Approved Definition: Protective relays
This report provides a survey of protective relaying technology and its associated com- munications technology used in today's power transmission systems. This report is divided in two parts. In the first part, the operating principles of relay applications and the main components of protection systems are briefly introduced.
