Monitoring electrolytic cell currents
First Claim
1. An apparatus, comprising:
- one or more sensors adapted to measure magnetic field strength generated about a conductor, said conductor adapted to carry electrical current to or from an electrolytic cell; and
a processor in electrical communication with one or more of said sensors for determining a compensated magnetic field strength generated about said conductor by compensating said magnetic field strength for other magnetic fields generated by other conductors adapted to carry electrical current to or from said electrolytic cell.

Abstract
For an electrolytic cell, an apparatus and method are described that use one or more sensors to measure magnetic field strength about a conductor carrying electrical current. A processor is in electrical communication with the sensors and determines a compensated magnetic field strength based on the magnetic fields of other conductors that also carry electrical current to or from the electrolytic cell. The processor uses this compensated magnetic field strength to determine the cathode electrical current carried by the conductor and to identify open and short circuits between the anodes and cathodes of the cell. The described apparatus and method account for interactions between the magnetic fields of the neighboring cathodes.
