Look up the permissible temperature limits for your specific cable insulation type. For instance: Peak short-circuit limit of 250°C.
To understand the genius of IEC 60949, you must first understand the concept of "adiabatic" heating. The traditional, simpler method for calculating short-circuit thermal effects assumes an , which means it assumes all the heat generated by the fault current is trapped inside the conductor itself. In reality, this is not entirely accurate. Iec 60949 Pdf Free Download
Standards are periodically amended or revised. Using an outdated version can lead to calculation errors, structural failures, or project rejections by regulatory inspectors. Look up the permissible temperature limits for your
