If NERC states that an IROL must be corrected as soon as
possible, but no longer than 30 minutes, but the RC has
indicated that an existing IROL has a Tv of 15 minutes,
which is true about the time to mitigate the IROL
exceedance
A. If NERC and the RC cannot agree utilize your best
judgment
B. The RC can have a more restrictive time imposed to
correct the IROL so you should use the 15 minute criteria
C. Request the RC to bring up the issue at the next RC
working group meeting and utilize the 30 minutes
D. NERC States 30 minutes and that is what you should
adhere to Correct Answer B. The RC can have a more
restrictive time imposed to correct the IROL so you should
use the 15 minute criteria
Two parallel transmission lines are both rated for 450 MVA
and are currently at 320 MVA each. If one of the lines
trips, it will cause the other line to be loaded above its
rating by more than 150 MVA. What should you do if you
receive notification that due to a system emergency one of
the lines must come out of service?
,A. delay the outage until generation can be started
B. redispatch available generation and remove the line
from service
C. Take the line out of service and dump 150 MW of load
D. wait until the line trips out of service Correct Answer B.
redispatch available generation and remove the line from
service
If your system is experiencing dynamic reactive reserve
deficiencies, which of the following actions can be

,If a transmission line has an SOL of 1375 MVA, but due to
parallel flows from external entities interchange
transactions the actual flow is 1525 MVA, what action
should you take?
A. Ignore the limit because the parallel flows total 200
MVA which would bring your native usage down to 1325
MVA
B. Open the line until the external entities curtail the
interchange tags
C. Request the RC to initiate a loading relief procedure
D. Direct the external entities to shed 150MW of load
Correct Answer C. Request the RC to initiate a loading
relief procedure

paths except ___
A. insufficient resources
B. emergency actions for inability to purchase capacity

, If there is a large system disturbance and the frequency
meters from multiple locations within the BA show different
values, what would be the reasonable conclusion?
A. the info is not accurate
B. the system is in an islanded situation
C. there was a large loss of load
D. the system has blacked out Correct Answer B. the
system is in an islanded situation
If your system experiences the loss of 2000 MW of
generation that has caused the frequency to decline and
you have shed 300 MW of load to stop the frequency from
declining, what should you do if the frequency will not
come above 59.94 Hz?
A. restore the load and wait for RC direction
B. implement additional corrective actions to restore
frequency
C. wait until the system load drops off and monitor the
system frequency
D. request the region to perform a frequency decay
analysis Correct Answer B. implement additional
corrective actions to restore frequency
How long does a TO have to mitigate an IROL

B. 20 minutes
C. 30 minutes
D. 60 minutes Correct Answer B. 20 minutes
