Detuned harmonic filters are the series combination of a reactor and power capacitor. This filter offers higher impedance for high frequency harmonics. This prevents harmonic resonance and amplification. Common tuning factors of detuned filters are 7% and 14%

• 7% reactor mitigates 5th harmonic & above
• For industries with drives, converters & other power electronic devices
• 14% reactor mitigates 3rd harmonic & above
• For IT industries
• For industries with high single-phase non-linear load
