WKO series
Closed-loop converter
The REO current transformers of the WKO series work according to the proven compensation principle and are suitable for measuring direct and alternating currents.
The primary current generates the magnetic flux in the ferromagnetic core, which is compensated by a secondary coil. The current evaluation is realized with an electronic circuit and a Hall sensor. The secondary compensation current is an exact image of the primary current to be measured.
