SYMMETRICAL SHORT CIRCUIT CURRENT CALCULATION BY PER UNIT IMPEDANCE METHOD.

This video illustrate the basics of
1) Requirement of base MVA & KV consideration .
2) Calculation of per unit impedance of the various power equipment like Utility, Generator, Transformer, Motor, Cables etc.
3) Conversion of per unit Impedance with respect to base MVA&KV
4) Development Impedance diagram.
5) Demonstration of short circuit current calculation formula and related calculation
