Electricity suppliers require their customers to use harmonic blocking reactors to limit the impact of harmonic distortion caused by the increasing use of power electronic devices.
Our knowledge and experience gained since 1969 in the design and manufacture of transformers and reactors for the industrial world enable us to offer optimised and reliable quality products.
Harmonics limiting reactors
Blocking reactors, together with capacitor banks, create power factor correction and harmonic current filtering banks.
This type of reactor is usually constructed with a magnetic core that can guarantee high linearity values even with large increases in current compared to the nominal value.
A detuning power factor correction system prevents any amplification of harmonic currents and voltages caused by resonance between the capacitor and inductance capacitance of the electrical system.
By adding a correctly sized reactor to the power capacitor, a low resonant circuit is formed (usually below the fifth current harmonic) which prevents higher order harmonics from flowing into the capacitors and damaging them.
