ELECTRICAL ENGG.

The major topics in Power Systems can be listed as follows: Transmission and Distribution The first topic under this unit is overhead transmission lines and in this topic first you need to memorize the expressions for Inductance and Capacitance for both Single Phase and Three Phase Lines. So you should practice some problems based on this which involve the computation of GMD and GMR. The next topic that you should cover is modelling of Short and Medium Transmission Lines as Long Transmission Lines is not much important in Steady State Analysis and Short Transmission Line is most important. Here you should also focus on the A,B,C,D Parameters of the line and the power expressions in terms of A,B,C,D and remember the approximate voltage regulation in Short Transmission Line which is same as Transformer. The next topic under this unit is Surges and in that topic you need to memorize the thevenin equivalent circuit for analysis of surges and by that you can easily calculate the Tr...
