Q: What is the primary function of a power system?

To generate, transmit, and distribute electrical power efficiently and reliably. — Power systems are designed to deliver electricity to consumers.

Q: Which component is used to step up or step down voltage levels?

Transformer — Transformers are crucial for voltage transformation in power grids.

Q: What type of current is typically used for long-distance power transmission?

AC (Alternating Current) — AC is generally preferred due to easier voltage transformation.

Q: What is the purpose of a circuit breaker?

To protect the circuit from overcurrents. — Circuit breakers interrupt the circuit during faults.

Q: What is the unit of electrical power?

Watt (W) — Power is measured in Watts.

Q: Which of the following is a renewable energy source?

Solar — Solar energy is derived from the sun and is a renewable resource.

Q: What does 'HV' stand for in the context of power systems?

High Voltage — HV is a common abbreviation for High Voltage.

Q: What is the function of a substation?

To change voltage levels and switch power lines. — Substations are key for voltage regulation and switching.

Q: What is the purpose of a fuse in a power system?

To protect the circuit from overcurrent. — Fuses, like circuit breakers, offer overcurrent protection.

Q: Which of the following components is primarily used for reactive power compensation?

Capacitors and Reactors — Capacitors and reactors help manage reactive power flow.
