Calculation Methodology
ConductorPro's short-circuit thermal effects report for bare conductors cites IEC 60865-1, IEC 60865-2 and IEC 60909-0:2021.
- IEC 60865-1
- IEC 60865-2
- IEC 60909-0:2021
These references identify the calculation methodology used. They do not indicate certification or independent validation of ConductorPro.
Inputs
Each assessment is defined by the conductor and the fault scenario.
- Conductor material
- Conductor cross-section
- Fault current
- Fault duration
- Frequency
- Initial and final conductor temperatures
Results
The calculation is followed by an explicit conclusion on whether the conductor has sufficient thermal strength for the case studied.
- Rated short-time withstand current density
- Thermal equivalent short-circuit current
- Equivalent current density
- Sufficient thermal strength: yes or no
