9. Q9: How many MVARs does a 230 kV, 50 MVAR capacitor bank provide
when the voltage is 207 kV?
A) 50 MVARs
B) 45 MVARs
C) 40 MVARs
D) 35 MVARs: C) 40 MVARs
10. Ql0: Voltage response to power flow is a study that is represented by
which of the following?
A) D Curve
B) P-V Curve
C) Ferranti Curve
D) VRS Curve: B) P-V Curve
11. Q11: Two adjacent lines exist in a Balancing Area that are the same
length and have the same ratings. One line is overhead and the other is
underground. How do these two lines respond as load picks up through the
day?
A) The overhead line will carry more of the load increase
B) The underground line will carry more of the load increase
C) The load increase will be distributed evenly over the two lines
D) The line with the higher impedance will carry more of the load: B) The
underground line will carry more of the load increase Feedback: EPRI Tutorial:
Due to its higher capacitive property, the underground cable will have lower
impedance and therefore carry more of the increase.

C) Located in the same station as other reactive resources
D) Located close to load areas: D) Located close to load areas

transmis- sion lines where Line A is 150 miles long and Line B is 15 miles
long. Which statement is true if both lines are lightly loaded?
