• Current Transformer Basics And The Current Transformer

A current transformer of say 5005, will produce 5 amps in the secondary for 500 amps in the primary conductor, 100 times greater. by increasing the number of secondary windings, ns, the secondary current can be made much smaller than the current in the primary circuit being measured because as ns increases, is goes down by a proportional amount.
