Home / Low-voltage circuit breaker relay protection commissioning
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. The testing and verification of relay protection devices can be divided into four groups: Type tests are needed to prove that a protection relay meets the claimed specification and follows all relevant standards. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. Each procedure includes the task, preconditions (work Status, needed documentation, involved personnel and measuring instrument used for. need to have a thorough understanding of switchboards, switchgear, circuit breakers and associated protective relays.
