FOCS applications and benefits

The main applications can be found where large dc currents need to be measured such as in aluminum smelters, dc arc furnaces, magnesium smelters or other.

In these plants, a precise and accurate current measurement for control, metering and efficiency calculation is needed. Due to the optical measurement and fully digital signal processing, the benefits for the user are manifold compared to similar dc measurement devices based on the Hall effect.

FOCS benefits:

  • High accuracy
  • High bandwidth: detection of current ripple and transients
  • Wide temperature range
  • Full digital processing
  • Uni- or bi-directional current measurement, to be specified
  • Instantaneous overcurrent trip or inverse time overcurrent trip on request
  • Instantaneous reverse current trip on request
  • Analogue and digital outputs
  • Easy to install, adaptable shape of sensing head
  • Small size and weight
  • No magnetic centering necessary
  • No magnetic overload problem
  • Insensitive to shock and vibration
  • Immune to electromagnetic interference
  • Electronics fully insulated from bus bars
  • Dielectric sensing head
  • Low power consumption
  • Low maintenance
