Overview of the “Standard for Interconnecting Distributed Resources with Electric Power Systems”, IEEE 1547 and it’s potential impact on operation of the Distributed Generation (DG) systems and on the design of the switchgear intended for the transition of the distributed generation resources (DR) to and from grid connected operation.
Short circuit interrupting ratings of the Low Voltage Generator Circuit Breakers. X/R ratio of a typical low voltage generator above 500kVA often exceeds the test X/R ratio of low voltage circuit breakers. Concise background of the importance of considering X/R ratio is presented along with hard to find derating data in table format, which should allow engineers to easily calculate derated value of circuit breaker based on system X/R ratio for any application.
