,Answer: B. Phasor Measurement Unit (PMU)
Rationale: PMUs provide synchronized real-time measurements of
electrical waves across the grid.
3. What technology enables automated fault detection in smart grids?
A. SCADA systems
B. Manual inspection logs
C. Paper-based reporting
D. Mechanical relays only
Answer: A. SCADA systems
Rationale: Supervisory Control and Data Acquisition (SCADA) systems
enable automated monitoring and fault detection.
4. What is the main advantage of distributed energy resources (DERs)?
A. Increased grid instability
B. Centralized power production
C. Localized energy generation near consumption points
D. Reduced energy efficiency
Answer: C. Localized energy generation near consumption points
Rationale: DERs reduce transmission losses by generating power closer to
users.
5. Which protocol is commonly used in smart grid communication?
© 2026 Academics_Excellence
,A. HTTP
B. DNP3
C. FTP
D. SMTP
Answer: B. DNP3
Rationale: Distributed Network Protocol 3 (DNP3) is widely used in utility
automation systems.
6. What is load balancing in a smart grid?
A. Increasing voltage randomly
B. Equal distribution of electrical load across the network
C. Disconnecting users during peak hours
D. Storing unused electricity in transformers
Answer: B. Equal distribution of electrical load across the network
Rationale: Load balancing ensures grid stability and prevents overload
conditions.
7. Which energy source is MOST compatible with smart grid integration?
A. Coal-only plants
B. Nuclear-only systems
C. Renewable energy sources
D. Diesel generators only
© 2026 Academics_Excellence
, Answer: C. Renewable energy sources
Rationale: Renewables like solar and wind integrate well due to variable
generation patterns.
8. What is the role of an Advanced Metering Infrastructure (AMI)?
A. Manual billing system
B. Real-time data collection and communication
C. Mechanical energy conversion
D. Voltage amplification
Answer: B. Real-time data collection and communication
Rationale: AMI enables smart meters to communicate usage data in real
time.
9. Which component protects smart grids from cyber intrusion?
A. Surge protector
B. Firewall system
C. Capacitor bank
D. Mechanical switch
Answer: B. Firewall system
Rationale: Firewalls monitor and control incoming and outgoing network
traffic.
