1. In a power system with negligible resistance, the three-phase
fault current at a point is 8 pu. The series reactance to be
inserted at the fault point to limit the short circuit current to 5
pu
2. A 3-phase, 15 MVA, 10 kV alternator has internal reactance of
6% and negligible resistance. Find the external reactance per phase
to be connected in series with the alternator so that steady
current on short circuit does not exceed 6 times the...
1a. What is thermodynamics system?
b. Briefly explain (i) control mass system
(ii) control volume system
c. Comment briefly on control mass system and control volume
system at Steadey state
d.
Draw block diagram of a sun tracking system for a solar power
system. Also mention the component clearly.
Note: give a small description of its
working.
1. Why don’t the short circuit and open circuit voltage produce
power in a p-n cell?
2. The power supplied by a solar cell is proportional to its
surface area. Using the flux of solar energy under AM1 conditions,
estimate the power a 1-cm2 solar cell will yield. State
explicitly any assumption you make.
What is a Tera-Tera system in a power system network mean and how does it operate? How does current flow from one earth electrode in a house to the electrode earth of the substation? like how does it take that path, if there is no connection between them; other than the fact they are both buried underground.
