= Thermally permissible short-circuit current (r.m.s. value in Amperes). Most global industrial projects require adherence to IEC
For those familiar with cable rating calculations, the adiabatic short‑circuit current is determined by the well‑known formula:
): The maximum continuous operating temperature of the cable before the fault occurs (e.g., 90°C for XLPE insulation). Final Temperature ( θftheta sub f
: The standard then provides a factor to account for heat transfer to adjacent materials, such as insulation or cable sheaths. A: Verify the authenticity of an IEC 60949
The standard modifies the traditional adiabatic short-circuit formula by introducing a non-adiabatic factor. The Adiabatic Base Formula
