🔍 Key Concepts

• How a clamp-on AC ammeter measures current without breaking the circuit • The difference between a current transformer and a potential (voltage) transformer • Why a split-core is needed around a conductor carrying AC

💭 Think About

• Ask yourself: does this instrument need to sense current in a single conductor or the voltage across two points? • Which transformer type is specifically designed to have the primary as the conductor itself passing through a magnetic core? • Consider what role the secondary winding plays in safely scaling down a large line quantity (current or voltage) for measurement.

✅ Before You Answer

• Verify which transformer type is normally used with ammeter circuits for measuring line current indirectly. • Check which transformer type commonly uses a single turn primary formed by the conductor passing through the core. • Confirm that the split-core design allows the meter to clamp around a live conductor without disconnecting it.
