Measurement, Control & Protection for 

Electro-Processes and High Power Conversion



Electrolysis is the most cost effective method for volume production of Magnesium. A high DC current is passed through a Magnesium Chloride solution in a closed cell at a temperature of around 700C. The chlorine gas given off by this electrolysis is recovered for re-use. The remaining Magnesium can then be easily extracted. Modern magnesium process technology utilizes current approaching 350kA to achieve significant improvements in current efficiency while maintaining environmental compliance.

Process Applications
High accuracy measurement of voltage and current is needed to…
  • Provide current data to process control systems for optimum control performance
  • Detect unexpected changes in process efficiency
  • Accurately evaluate impact of intended / trial process changes
  • Objectively compare multiple process lines
  • Improve visibility of process energy utilization and costs

  • Power Conversion Applications
    The Magnesium refining process is most efficient with highly stable and reliable from power conversion equipment. Current instability leads to numerous process efficiency problems thereby increasing the costs. Such instability can cause process cell damage and even endanger staff and facility.

    Highly dependable and responsive measurement systems are needed to
  • Provide current data to rectifier control systems for optimum performance and stability
  • Provide overall multi-rectifier balance indication
  • Provide a backup ‘totalized’ current measurement signal for total mainline current
  • Sense power conversion equipment failure modes quickly to protect process, equipment and personnel.
  • Analyze rectifiers condition to determine maintenance requirements as well as acceptance testing of new/replacement rectifiers
