HARMONIC FILTER REACTORS

Detuned Harmonic Filter Reactors, are used in series with capacitor banks in power factor correction units. By using these types of detuned reactors it is possible to avoid following negative effects on system.

• Overcurrent during switching on the capacitor banks
• Overload of capacitor banks because of the harmonic resonance.
• Short lifetime on capacitors
• Overheating of the utility transmission cables.
• Overheating of the distribution transformer.
• Unintended triggering of the protective devices.
• Distortion of utility voltage waveform and problems on voltage sensitive devices
• Interferences on data transmission systems
• Unexplainable faults in electronic boards

Chosing the correct detuned filter reactor and capacitor value on detuned power factor correction systems is very important. To obtain optimum performance form a detuned power factor correction system following criteria must be controlled and met during the pairing of the reactors and capacitors
