The primary purpose of de-tuning reactors in a capacitor bank, is to prevent a phenomenon in the electrical system known as harmonic resonance. Resonance can have a devastating effect on electrical equipment, and is the main reason why older capacitor banks fail and cause problems in a facility's power distribution system.

There was once a time when very few Cos Phi capacitor banks had de-tuning reactors, and a power quality study would be performed to determine if they were necessary. Nowadays with the rise in use of devices with switch-mode power supplies, almost all Cos Phi capacitor banks come with de-tuning reactors, and a power quality study must be performed to prove that they are not necessary.


Features:

  • Air gap between windings allows for better cooling. With proper enclosure cooling, no thermocouple is needed. Temperature sensors available upon request.
  • Copper windings
  • 7% impedance (Z), 14%Z available upon request

Data sheets and stock parts list coming soon!
