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.
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.
Consider the following statements:
i) Power + P(Type II Error) = 1.
(ii) If a hypothesis test is performed at the 5% significance
level, and if the null hypothesis is actually true, then there is a
5% chance that the null hypothesis will be rejected.
(iii) If a hypothesis is tested at the 5% significance level
with a given data set, then there is a lower chance that the null
hypothesis will be rejected than if that same hypothesis is...
