Overview















ABB unique





Closed loop Hall effect technology











ABB current sensors based on closed loop Hall effect technology are electronic





transformers. They allow for the measurement of direct, alternating and impulse





currents, with galvanic insulation between the primary and secondary circuits.





The primary current IP flowing across the sensor creates a primary magnetic flux.





The magnetic circuit channels this magnetic flux. The Hall probe placed in the





air gap of the magnetic circuit provides a voltage proportional to this flux.





The electronic circuit amplifies this voltage and converts it into a secondary current





IS. This secondary current multiplied by the number of turns NS of secondary





winding cancels out the primary magnetic flux that created it (contra reaction). The





formula NP x IP = NS x IS is true at any time. The current sensor measures





instantaneous values.











Features





















Galvanic insulation between the





primary and secondary circuits.





Measurement of all waveforms is





possible: direct current, alternating





current, impulse, etc.





High accuracy over a large frequency





range (from direct to more than 100kHz).





High dynamic performance.





High overload capacities.





High reliability.











Application
