WKO current sensors work in accordance with the proven compensation principle and are suitable for measuring direct, alternating and mixed currents.
The primary current generates a magnetic flux, which is compensated by an internal secondary coil. The current is evaluated by an electronic circuit and a Hall sensor. The secondary compensating current is a precise representation of the primary current to be measured.
