What is detuned harmonic filter?
What is detuned harmonic filter?
The harmonic filter (Detuned) is to limit the flow of harmonic current from non-linear loads on the reactor to the fixed impedance loads (eg capacitor). An unwanted state will occur on the capacitor due to the harmonic current.
What is tuned and detuned filter?
Single-tuned filter and the detuned reactor is the type of harmonic filter that commonly used to mitigate harmonic distortion. The harmonic filter also has benefit to improve power factor and voltage profile on the system.
How many harmonic filters are available?
There are three main classifications of filters: (1) passive, (2) active, and (3) hybrid filters: 1. Passive filters are made up of reactive components like capacitors, inductors, and resistors. They are tuned to provide a low impedance path for specific currents with undesirable harmonic frequencies.
What is a detuned filter?
Detuned filtering is a reliable and time-tested method to improve the power factor and also mitigating the risk of resonance; this is achieved by shifting the resonance frequency to lower levels, thereby ensuring that no harmonic currents are present.
Why are detuned reactors required for APFC panels?
The harmonic filter (Detuned) is to limit the flow of harmonic current from non-linear loads on the reactor to the fixed impedance loads (eg capacitor). To reduce the harmonic coupling current we need to increase the line impedance to which the capacitor is connected.
Why we use active harmonic filter?
Active Harmonic Filters – Also known as active harmonic conditioners, these filters are often used in commercial installations with loads less than 500kVA. They help to reduce current distortion that could lead to equipment heating and circuit overloads.
How does a detuned reactor work?
What are Detuned reactors? Detuned Reactors prevent harmonic amplification caused due to RESONANCE and avoid the risk of overloading capacitors, thereby significantly reducing voltage and current harmonic distortion in the network. To avoid this problem, it is common to insert reactors in series with capacitor banks.

What is detuned reactor?
Detuned reactors, that are three-phase inductors dedicated to attenuate the amplification of harmonics in harmonic rich networks, protect the different components of the installation.
