Question 1 of 27070

What is the purpose of a potential transformer in an electric circuit?

🔍 Key Concepts

• Potential transformer (PT) function in AC (alternating current) systems • Difference between changing voltage levels and changing current type (AC vs DC) • Difference between electrical and mechanical energy conversions

💭 Think About

• Which device is normally used in power systems so that meters and protective relays can safely measure high voltages? • Does a potential transformer create new power, or does it work with voltage that already exists in the circuit? • Which option describes a function that specifically deals with voltage level, not with converting AC to DC or producing mechanical motion?

✅ Before You Answer

• Make sure the option you choose mentions voltage, not current type or mechanical motion • Confirm the device is used to adjust or reproduce voltage at a different, usually safer level, not to generate power • Eliminate any choice that talks about converting AC to DC or driving a motor/mechanical load
