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