1. INTRODUCTION Protection is the branch of electric power engineering concerned with the principles of design and operation of equipment (called ''relays'' or ''protective relays'') that detects abnormal

LECTURE NOTES ON ELECTRICAL POWER SYSTEM

For operation of CB a relay is necessary. A protective relay is a device that detects the faults and initiate the operation of the circuit breaker to isolate the defective element from the rest of the system.

Essential Qualities of Protection Systems:

Protection Systems in which selectivity is relative are non-unit systems. Examples of the former are differential protection and frame leakage protection, and of the
