NERC Transmission Operator Exam
1. Which entity is responsible for real-time operating reliability of
the bulk electric system within a specified area?
A. Regional Entity
B. Balancing Authority
C. Transmission Operator
D. Reliability Coordinator
Rationale: The Transmission Operator is responsible for real-time
reliability of its portion of the BES.
2. The purpose of the Transmission Operator’s Operating Plan is to:
A. Provide financial forecasts
B. Schedule maintenance outages
C. Ensure reliable operation during normal and emergency
conditions
,D. Manage customer billing
Rationale: Operating Plans outline actions needed to maintain
reliability in all conditions.
3. A System Operating Limit (SOL) is best defined as:
A. A maximum generator output
B. Seasonal load forecast
C. A limit that ensures operation within acceptable reliability
criteria
D. A control area boundary
Rationale: SOLs prevent violations of system reliability criteria
(voltage, thermal, stability).
4. A Transmission Operator must notify the Reliability Coordinator
when a potential SOL violation is expected within:
A. 60 minutes
B. 30 minutes
C. 24 hours
D. 5 minutes
Rationale: RC notification requirements generally enforce a 30-
minute window to report anticipated violations.
5. An IROL exceedance must be mitigated within:
A. 60 minutes
B. 30 minutes
C. 10 minutes
D. 30 minutes or less
,Rationale: Standards require IROL exceedances to be resolved
within 30 minutes.
6. Which entity has “wide-area view” of the electric system?
A. Balancing Authority
B. Transmission Owner
C. Reliability Coordinator
D. Generator Operator
Rationale: The RC oversees multiple areas and maintains a wide-
area reliability perspective.
7. The primary purpose of a remedial action scheme (RAS) is to:
A. Reduce customer outages
B. Automatically maintain system stability during contingencies
C. Provide voltage support
D. Optimize market performance
Rationale: RAS systems act quickly to preserve stability during
unexpected events.
8. The TOP must have real-time monitoring capable of:
A. Measuring only local voltages
B. Monitoring flows, voltages, and system conditions
C. Predicting next-year load
D. Market performance monitoring
Rationale: Real-time situational awareness requires comprehensive
system monitoring.
, 9. Voltage instability is most often caused by:
A. Generator outages
B. Insufficient reactive power support
C. Over-frequencies
D. Weather changes
Rationale: Reactive shortages reduce voltage support and can
trigger instability.
10. The primary function of Automatic Generation Control (AGC) is:
A. Reducing maintenance costs
B. Balancing load and generation in real-time
C. Protecting transformers
D. Measuring frequency
Rationale: AGC continuously adjusts generation to maintain
balance and frequency.
11. A Transmission Operator must be staffed:
A. Only on weekdays
B. 24/7 with trained operators
C. During peak hours only
D. By engineers only
Rationale: Bulk system operations require continuous staffing for
reliability.
12. Reactive power is used primarily to:
A. Increase energy output
B. Support voltage levels
