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. 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 ca

1. Protection systems. Protection equipment is necessary to detect and isolate faults from the system. Protection relays detect faults by comparing the quantity (and angles in some cases) of the primary circuit current or voltage to a pre-determined setting.

Protection Schemes for Electrical Power System

Power system protection''s main objective is to maintain the reliability of the running power system and to save the equipment from getting damaged. To achieve reliability, two points are kept in mind: Only the faulty part of the system is completely isolated within a minimum time so that the remaining system operates normally.
