Individual commissioning of relay protection devices
This paper suggests a process for performing consistent and thorough commissioning tests through many sources: breaking out relay logic into schematic drawings; using SER, metering, and event reports from relays; simulating performance using end-to-end testing and lab. This paper suggests a process for performing consistent and thorough commissioning tests through many sources: breaking out relay logic into schematic drawings; using SER, metering, and event reports from relays; simulating performance using end-to-end testing and lab. Abstract—Performing tests on individual relays is a common practice for relay engineers and technicians. Most utilities have a wide variety of test plans and practices. However, properly com-missioning an entire protection system, not just the individual relays, presents a challenge. Since the basic function of a protection relay is to correctly function under abnormal. Relay systems protect high-voltage equipment and transmission lines to ensure safe, stable systems. The information provided here is restricted to general notes regarding the procedures.
