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. 517 $aANSI/IEEE Std C37.081-1981: IEEE Guide for Synthetic Fault Testing of AC High-Voltage Circuit Breakers Rated on a Symmetrical Current Basis 606 $aElectric circuit-breakers 615 0$aElectric circuit-breakers. 676 $a621.317 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a996279562503316 996 $aANSI$92072434 997 $aUNISA
