why we need.
How to design a Unit auxiliary transformer for a power house
having a unit of 65 MW and Generating voltage of 11 KV and
Secondary voltage of 433V
we have a lot of model of rectifier but thyristor rectifier
is the most rectifier that use in power system. Do you know
why this rectifier is used?
Give me the calculation steps to design an electromagnet to

Can Anyone Answer anyone of these ?
Q1) why direct SOLUTION of Load Flow Studies in Not Possile ?
Q2)Why majority of Buses in power system are load buses
Q3)Why one of the buses in Power system is taken as reference bus (slack or swing) Bus ?
Q4)Bus Admittance Matrix is a sparce (means it contains some zero elements ) matrix , give reason
With a phasor diagram show the effect of increasing the field current of a generator supplying a constant real power and connected to a grid system.
why do you add the load short circuit impedance when
considering short circuit amperage. It seems that you should
only consider supply.
If you need to consider loads and you don't know what loads
are to be added , what would be a good sub-transient
reactance rating for the loads?
what causes contact chatter when there is no demand on the
air conditioning unit?
explain supply side and demand side energy management with
advantages & disadvantages
