Common Mode Chokes When we said a common mode choke, it means it was wound both line and neutural windings on a single core. Since the noise would be common mode noise usually, the way to lower (if not eliminate) the unwant noise frequencies is to use a common mode choke As below picture show us details of Common-Mode Signals Defined: Such signals can arise from one or more of the following source...

A zero-flux current transformer is used to measure a current flowing in a conductor (so-called primary conductor). The zero-flux current transformer has an electrical detection winding with which the magnetic flux generated by the flowing current and surrounding the conductor is measured. The zero-flux current transformer further has an electrical compensation winding, with which the magnetic flux...
