Describe (i) Clamp meters (ii) Instrument transformers.

(i) Clamp Meters: A clamp meter, also known as a current clamp meter or amp meter, is an electrical measuring device used to measure the current flowing through a conductor without the need to disconnect it from the circuit. This type of meter is commonly used in electrical testing and troubleshooting. Clamp meters can measure both AC and DC currents and provide a non-intrusive method for measuring electrical currents.

A clamp meter works by using a magnetic field to measure the current flowing through a conductor. The clamp meter has two jaws that can be opened and closed around the conductor. When the jaws are closed, a magnetic field is generated around the conductor. ____ _________ _____ ___ _________ _________ _________ _______.
