Grading Capacitors- Air Insulated Switchgears

Product Description

Capacitor Products, such as Coupling Capacitors, Transient Recovery Voltage Capacitors or Grading Capacitors are used within HV networks for various purposes. Examples are: coupling high frequency carrier signals to the power line as well as (in combination with CB) reducing transient over voltages, ensuring uniform voltage distribution or increasing the switching capacity of a breaker.

Grading Capacitors are used in combination with High Voltage Circuit Breakers with different purposes.

• Multi break Circuit Breakers:
• Grading Capacitors ensure uniform voltage distribution across all contacts points during normal and switching system operation
• Single break Circuit Breakers:
• Grading Capacitors can be used to increase the switching capacity of the breaker
• 90 up to 300 kV
• Sealed construction, maintenance free
• All external metallic components made by aluminum or in ox steel
• High customization range to match CB mechanical and electrical parameters
• High mechanical resistance to shock and vibration due CB  switching operation
• Available in compliance with all international standards
