Method: IEEE - X/R is calculated from separate R & X networks. Protective device duty is calculated based on total fault current. The multiplication factors for high voltage circuit-breaker and high voltage bus momentary duty (asymmetrical and crest values) are calculated based on system X/R. * Indicates a device with momentary duty exceeding the device capability

Method: IEEE - X/R is calculated from separate R & X networks. HV CB interrupting capability is adjusted based on bus nominal voltage Short-circuit multiplying factor for LV Molded Case and Insulated Case Circuit Breakers is calculated based on asymmetrical current. Generator protective device duty is calculated based on maximum through fault current. Other protective device duty is calculated based on total fault current. * Indicates a device with interrupting duty exceeding the device capability ** Indicates that the circuit breaker has been flagged as a generator circuit breaker. However, ETAP could not detect a single path, without a transformer, to the specified generator. Therefore, this circuit breaker is treated as a regular circuit breaker in short-circuit calculations.
