  • Other characteristics:



Constructive Characteristics - Three phase harmonic filters are made of low
losses magnetic plates, permanent regime class F (1550
C) copper conductor
and thermal protection relay.
With the purpose of increasing filters ventilation, windings are separated
among them, improving thermal dissipation.
Available factor p is 7% and 14% with resonance frequency 189 Hz and 134
Hz for 50 Hz networks.
With this standard values in three phase networks and balanced loads, the
5th (250 Hz) harmonic and higher resonant 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, caused by harmonics.
