The standard uses a three-step approach to determine the safe current limit for a cable during a fault: Calculate the Adiabatic Short-Circuit Current ( IADcap I sub cap A cap D end-sub
However, it is essential to respect intellectual property. The IEC relies on sales of standards to fund ongoing development of safety-critical documents.
To use the standard effectively, you need several specific inputs: IEC 60949:1988
is a technical document used by electrical engineers to determine how much fault current a cable can safely handle. Accessing the Standard
: It employs a "modifying factor" approach—you calculate the simple adiabatic current first, then multiply it by a factor to get the actual permissible current .
IEC 60949 is critical for sizing conductors and protective devices to prevent thermal damage during short-circuit events. It improves upon the simpler "adiabatic" method by accounting for heat that dissipates into surrounding materials. The standard follows a three-step calculation approach:
