Guidelines are established for synthetic testing of circuit breakers, as well as test criteria for demonstrating the short-circuit current rating of circuit breakers on a single-phase basis. Criteria for evaluating results are also provided. The standard covers short-circuit current interruption process; basic principles of synthetic testing; synthetic test circuits; requirements for synthetic test methods; parameters, test procedures, and tolerances; short-line fault; multiple loops; circuit breakers equipped with parallel impedance; duty cycle; and test records.ANSI/IEEE Std C37.081-1981: IEEE Guide for Synthetic Fault Testing of AC High-Voltage Circuit Breakers Rated on a Symmetrical Current BasisElectric circuit-breakersElectric circuit-breakers.621.317NjHacINjHaclDOCUMENT996279562503316ANSI2072434UNISA
