Current clamps

A current clamp – also called ‘ampere rod’ – is a particular type of an ampere meter intended to measure with alternating current or direct current.

Current clamps are very convenient measuring instruments with which one can measure current in a conductor, without having to break the circuit. If we perform power measurements with a conventional multimeter we must interrupt the wiring and connecting the device to the circuit under test. Rather, we use a clamp, then we can measure flow by surrounding the clamp around a conductor. One of the advantages of this method is that we can measure even a heavy current without turning off the circuit during a test.

Current clamps are available in many sizes and designs:

• AC current clamps
• AC/DC current clamps
• Leakage current clamps (for measurement of very low currents)
• AC current clamps (for use with multimeter or other measuring device)
• AC/DC current clamps (for use with multimeter or other measuring device)
• Flexible current clamps or hard beak clamps
• Large and small beak
