Original practice questions
These are preparation examples, not questions attributed to this employer.
What are the key components of a power transmission system? A power transmission system typically includes transmission lines, substations, transformers, and circuit breakers. These components work together to transport electricity from power plants to distribution networks.
Explain the working principle of a transformer. A transformer operates on the principle of electromagnetic induction, transferring electrical energy between two or more circuits through inductively coupled conductors—the transformer's coils.
What is the difference between AC and DC transmission? AC transmission involves alternating current, which changes direction periodically, while DC transmission uses direct current, which flows in one direction. AC voltage is readily transformed, while HVDC can be advantageous for suitable long-distance links, submarine cables and asynchronous interconnection; compare the whole system including converter stations.
How do you calculate the efficiency of an electrical machine? The efficiency of an electrical machine is calculated by dividing the output power by the input power and multiplying by 100 to get a percentage.
What are the advantages of using high voltage for power transmission? High voltage reduces the current for the same power level, which decreases resistive losses in the conductors and improves the efficiency of power transmission.
Describe the role of a circuit breaker in a power system. A circuit breaker is a protective device that automatically interrupts the flow of electricity in a circuit as a safety measure to prevent damage from overloads or short circuits.
