DC Capacitors

Coupling Capacitor (CC)

  • Utilized in HVDC applications in conjunction with thyristor valves and can be used for Transient Recovery Voltage (TRV) control in substations
  • DC Capacitors are also used for any kind of HV test systems


  • Available from 10 kV up to 800 kV
  • Serial resistance
  • Sufficient grading current
  • High seismic withstand design
  • Oil insulation
  • Composite or porcelain insulator
  • Reducing/filtering transient overvoltage & harmonics
  • Coupling and de-coupling of HF-signals
  • Built-in parallel grading resistor to guarantee an even voltage distribution
  • Connecting of line fault locator
  • Available in compliance with all international standards
