Fault Analysis with Applied Symmetrical Components

PSA400 is a must course for electrical engineers, electricians and electrical engineering professionals who wanted to gain understanding how symmetrical component as a tool is used in Fault Analysis and Protective Relaying.

This course covers theory of the symmetrical components but more importantly explains how this analysis tool is applied in power system protection.
