Power System Interconnection Quiz

What is one of the advantages of power system interconnection?

• Increased plant reserve capacity

• Decreased reliability of supply

• Use of newer power plants

• Exchange of peak load

Which of the following is NOT an advantage of power system interconnection?

• Economical operation

• Use of older power plants

• Increased plant reserve capacity

• Reduced plant reserve capacity

Renewable sources of energy from the list would be

• Wind and solar

• Gas and oil

• Coal

• Nuclear

The efficient way of electricity transmission would be

• High voltage/ low current method

• High current/ Low voltage

• DC

• Very large conductors

Fuses are used to protect electrical plant and apparatus by acting as

• The weakest link for overcurrents

• A voltage sensitive link

• A surge protector

• A fault monitor

Which protection device is designed to interrupt the flow of electricity in the event of an overload or short circuit?

• Relay

• Capacitor

• Inductor

• Circuit Breaker

What is the primary function of a circuit breaker?

• To increase the current flow in a circuit

• To provide a continuous power supply

• To protect an electrical circuit from damage caused by overcurrent/overload or short circuit

• To reduce the voltage in a circuit

What does power system interconnection mean?

• Several power generating stations are connected and operated in parallel

• A single power generating station operates independently

• Power is generated and consumed at the same location

• Power is stored in batteries for later use

Why is power system interconnection done?

• To reduce the cost of power generation.

• To ensure robustness of the system and improve the reliability of power supply.

• To increase the voltage of the power supply.

• To decrease the power consumption.

What is one of the benefits of power system interconnection?

• It makes it easy to transfer power between consumers

• It reduces the need for power generation.

• It increases the cost of power supply

• It decreases the efficiency of power generation
