This presentation reviews the established principles and the advanced aspects of the selection and application of protective relays in the overall protection system, multifunctional numerical devices application for power distribution and industrial systems, and addresses. The selected protection principle affects the operating speed of the protection, which has a significant im-pact on the harm caused by short circuits. Protective relays and devices have been developed over 100 years ago to provide "lastline"of defense for the electrical systems. A big difference between conventional electromechanical and static relays is how the relays are wired. Synchrophasor technologies are being rapidly deployed to provide high-speed, high-resolution measurements from phasor measurement units (PMUs) across the transmission systems as a tool for monitoring and post fault analysis which may lead to real-time control using PMU data in near future. Literature review of the problems associated with the increased penetration of distributed generation (DG) in distribution networks in chapter 2 of this thesis has revealed among other things, the possibility of reverse power flow through the network which will impact on the reliability and.
