Relay protection device reports frequency abnormality
In electrical engineering, a protective relay is a relay device designed to trip a circuit breaker when a fault is detected. They are intended to quickly identify a fault and isolate it so the balance of the system. The Type 81 frequency relay is a reliable solid state relay designed to provide accurate detection of abnormal frequency conditions on electrical power systems The Type 81 frequency relay is a reliable solid state relay designed to provide accurate detection of abnormal frequency conditions on. Abstract-The paper describes the use of automated analysis reports and field recorded signals in troubleshooting protection system operation. Utilizing automated analysis of field-recorded data dramatically expedites the process of setting up test equipment and choosing and creating test.
