Short Circuit Analysis Software - IEC |
| |
| ETAP Short Circuit calculation software complies with IEC standards including IEC 60909 and IEC 61363. |
| |
Key Features |
- 1-pole / 2-pole short circuit device duty for single-phase panel / UPS systems
- Unbalanced L-G, L-L, & L-L-G fault current analysis
- Transient short circuit calculations using IEC 61363
- Compares device ratings with calculated short circuit values
- User-definable voltage C factor
- Service or ultimate short circuit current ratings for LVCB breaking capability
- User-definable R/X adjustment methods for Ip (method A, B, or C)
- Phase-shifting transformers
- Negative or positive impedance adjustments for max/min I"k & Ik
- Automatic application of K correction factors (i.e., KT, KG, KSO)
- Automatically determines meshed & non-meshed networks for calculating Ib, Ik, & Idc
- Ib for meshed network is adjusted by individual machine contributions for improved accuracy
- Considers both near & far short circuit current from generators
- Generates relay test set compatible plots for transient short circuits
- Detailed IEC device duty reports & complete contributions for unbalanced faults
