  • Linear-Measuring System Saves Space
    can also attract dirt. The most rugged solution for highly accurate position sensing, says Keller, is an inductive linear-measuring device integrated in ball and roller-rail systems. The linear-motion guides have a graduated scale with a precise pitch of 1,000 m. Pitch is etched into the scale
  • Case Study: Sensors for Conditioning Monitoring High Voltage Switching
    of mains electricity is an important function for preventative maintenance to ensure continuity of supply to consumers. The high voltage switchgear at major power distribution facilities operates in a very harsh environment with very high voltages and very fast movements. The condition

  • High-five to high-side current sensing
    through the meter. The technique was called high-side current sensing. However, high-side shunts require isolation in modern electronic control systems because of their direct connection to the high-side voltage rail. Current transformers perform this service in ac power systems. But the size and cost
  • Capacitor Engineering Bulletin: Polarization and Leakage Current Characterizations of High Voltage, Film Capacitors
    It is an unfortunate fact that "real" capacitors differ from ideal capacitors in many respects. Real capacitors include parasitic inductance and resistance, and vary in capacitance with temperature, frequency and voltage. This is especially true in high energy density capacitors, where dielectric
