主　　题：Event report Fault analysis Relay 

摘      要：Introduction:Event reports recorded by intelligent electronic devices(IEDs)such as digital relays and fault recorders during disturbances depict the status and system parameters of the power *** relay settings and unknown system parameters can lead to relay misoperation but information regarding these are available by performing a comprehensive analysis of fault ***,it is necessary to regularly make a comprehensive assessment of the functioning of the relay to ensure reliable *** description:The objective of this paper is to demonstrate various aspects of evaluating relay performance and verifying circuit parameters which are used in relay settings using field data in two case *** and Evaluation:While scrutinizing the relay’s operation,this paper also presents key insights on verifying circuit parameters using the same relay event ***:The lessons learned from the case studies presented in this paper will equip a protection engineer to inspect the operation of a relay during a transmission line fault,help gain a better understanding of the fault event and take possible actions to prevent future occurrence of similar events.
