Short Circuit Calculation Report The short circuit calculation report is generated with ETAP 11.1.1 version. Short circuit calculation is worked out considering the following conditions: 1. We have considered 1000MVA as source fault level of grid as IS 2026-I,1977 2. Cables are not considered, however this will reduce further SC level. 3. Lumped load at 0.415kV bus is derived from Latest load list. 4. SC calculations are done in accordance with IEC 60909 Detailed short circuit calculation result for each bus is indicated as below:
