Three phase harmonic filters are made of low losses grain oriented magnetic plates, permanent regime class F (155 ºC) cooper conductor and 90 ºC thermal protection relay.

With the purpose of increasing filters ventilation,windings are separated among them, improving thermal dissipation.

For small powers, connections are made by connectors terminal block and for higher powers terminal are used.

Standard surge factor is 7% with resonance frequency of 189 Hz for 50 Hz networks and 227 Hz for 60 Hz networks.

With this standard values in three phase networks and balanced loads, the 5th (250 Hz) harmonic and higher resosnant phenomenons are eliminated avoiding resonance between inductive impedance and three phase capacitors for power factor correction and preventing network capacitors and capacitor banks for overloads and overtones.

Advantages

Ideal to eliminate the 5th /250Hz) and higher harmonics
