Measurement, Control & Protection for 

Electro-Processes and High Power Conversion

The DC Arc furnace process is quite dynamic and sophisticated. Very responsive and dependable control is needed to establish, stablize the initial arc then steadily ramp current to full load and maintain it accurately. To do this, the control system needs the most responsive and accurate feedback information possible. It can only control as well as the inputs it receives.

Highly dependable and responsive measurement systems are needed to
  • Provide instantaneous current data to rectifier control systems for optimum performance and stability
  • 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
