NERC Transmission Practice Test Questions & Answers
Differential relay
Which type of relay operates on
the premise of comparing the
flow in and out of the area of
protection?
Uncontrolled separation
Underfrequency load shedding is
set-up so that which of the
following does NOT occur?
Transmission Operator
Who is responsible to make sure
that the operation of voltage
control equipment is coordinated
with other impacted entities?
Reactive inadvertent
The coordination of voltage
schedules by system operators
would be utilized to reduce all of
the following EXCEPT
An increase in MVAR output
What should a system operator
expect to see if the generator
increases its excitation?
Increase generation at Bus A
A transmission line between Bus
A and Bus B has MW flow from
Bus B to Bus A. After the tripping
of a parallel line, the line flow
from Bus B to Bus A exceeds the
lines thermal rating. Which of the
following actions would assist the
operator in correcting the
problem?
System remains connected to the Interconnection
What is a major concern for a
System Operator during
emergency conditions?
Coordinate with the neighbors
If your system has lost a large
amount of customer load due to a
system disturbance, but has
remained connected to all of your
neighbors, what is the best
solution to consider?
Get under the voltage by placing capacitors in service while
maintaining operating limits
You report for work on a peak
summer day with expected high
temperatures and load. What can
you do to maintain an adequate
system voltage profile?
