Harmonic System for Industries: During the last years there has been a large modernisation of the
industrial production processes and a fast evolution in power
electronics, especially in the field of power converters such as
variable speed drives for DC motors, frequency converters, USP...
All these equipments have a common characteristic which is the
generation of harmonics currents that reduce the quaility of the
electrical energy.Naac completes its range of filtering inductors
with a range of electromagnetic harmonic eliminating devices named
Compensators. The functioning of these devices is based on the
cancellation and compensation of magnetic fluxes. The main
advantage of the Compensators in the absence of electronic
components and capacitors. The Compensators are therefore
maintenance free, have an extramely long lifetime compared with
other types of filters and are compatible with any electrical
installation.Problems:Malfunctioning and failure in electronic
equipment. Overheating and failure in transformers and cables. Overload and failure in capacitor banks. Low efficiency of transformer and cables. Tripping of protections without apparent reason. Interferences in communication networks. Causes:Low quaility electrical energy. Elevated harmonic distortion
in the voltage. Notches and transients in the voltage caused by power converters. Elevated harmonic distortion in the current. Resonance in capacitor banks. Elevated true RMS current in the phases. Low power factor due to harmonics.Harmonic Compensator H2OF: The H2 Of series Compensator achieves the highest protection level
for industrial installations. An elevated level of filtering of the
5th, 7th, 17th, and 19th harmonic is obtained in combination with
galvanic isolation of the entire load. In order to obtain in
combination with galvanic isolation of the entire load. In order to
obtain a correct filtering it is necessary to install as well a RTL
line inductor with each DC converter or frequency converter. The
H2OF Compensator consists of two secondary windings. Each secondary
should supply 52 % of the load to be filtered. All harmonics are
compensated in the secondary windings and do not circulate through
of the electrical installation.The H2OF provides additional
advantages such as: reduction of electromagnetic disturbances,
optional voltage adaption between input and output and the
possibility use independence earths, as the neutral is isolated
from the mains. 10 kVA - 250 kVA H20F H20F+LTNReduction of phase currents up to20% 35%Reduction of voltage and current distortion up to 60 % 85 %Obtain power factor up to 0.95 0.98Galvanic isolation between input and outputIncludes thermal
