Q2. What is the difference between Current Transformers (CT) and Potential Transformers (PT)?
Ans. 
CTs measure current, while PTs measure voltage in electrical systems for protection and metering.
• CTs are used to step down high current levels to a manageable value for measurement.

• PTs are used to step down high voltage levels to a lower value for measurement.

• Example of CT: Used in power plants to monitor generator output.

• Example of PT: Used in substations to monitor line voltage.

• CTs provide current input for protectiv...read more

Q3. What is the difference between a fuse and a circuit breaker?
Ans. 
A fuse is a one-time protective device, while a circuit breaker can be reset after tripping due to overload or short circuit.
• Fuses melt to break the circuit, while circuit breakers trip and can be reset.

• Fuses are typically cheaper and simpler, but circuit breakers offer more convenience.

• Example of a fuse: glass tube fuse in household appliances.

• Example of a circuit breaker: automatic reset circuit breaker in electrical...read more
