INTRODUCTION TO POWER SYSTEM PROTECTION & RELAYS PPT

Power Systems Protection -Introduction Protective System – What are the Requirements? ¾ Speed The relay must operate at the required speed. It should neither be too slow which may result in damage to the equipment nor should it be too fast which may result in undesired operation. Damage can be Minimised. ¾ Sensitivity The relaying equipment must be

Protection schemes and zones | PPT | Free Download

The power system is protected through a zone protection scheme where the system is divided into sections, with each zone having one or more protective relays coordinated with the overall protection system. The zones are arranged to overlap so that no part of the system remains unprotected, and circuit breakers are located in the overlapped regions.

3. PROTECTION SETTINGS: INTRODUCTION A power system is composed of a number of sections (equipment) such as generator, transformer, bus bar and transmission line. These sections are protected by protective relaying systems comprising of instrument transformers (ITs), protective relays, circuit breakers (CBs) and communication equipment. In

Power System Protection

In Figure 1, the protection zones of a simple power system are shown. Each zone protects a single element of the power system. The protection zones overlap around circuit breakers. The purpose is to protect all sections of the power system. Typical zones of protection with transmission lines, buses, and transformers, each reside in its own zone.
