	A current transformer is made of a [[transformer]] surrounding a [[current]]-carrying [[conductor]]. The conductor serves as the primary for the transformer. The current passing through the conductor generates a [[magnetic field]] which cuts through to the secondary winding generating a secondary current proportional to the current through the primary (conductor). This device is useful as a current measuring device because it allows ratio to be applied where the full current doesn't matter. For example a 600:1 current transformer would generate 1 [[amp\|A]] of secondary current for every 600 [[amp\|A]] of primary current. This is extremely useful to have for the [[electrical grid]] because it allows for the measurement of high-current values without having to interrupt operating circuits.<ref name=B/>		A current transformer is made of a [[transformer]] surrounding a [[current]]-carrying [[conductor]].
