HARMONIC FILTER REACTORS

Harmonic distortions caused by non-linear loads in energy systems cause serious problems in industrial facilities. The causes of harmonic distortions and the problems that are frequently experienced due to these distortions are summarized below;

CAUSES OF HARMONIC DISORDERS

uninterruptible power supplies,

motor starters,

motor drivers,

Speed control devices Computer and electronic lighting Welding machines,

power electronics converters

Rectifiers and similar devices increase the harmonic distortion in the network.

MAIN FAULTS CAUSED BY HARMONIC DISORDERS

Heating in electromechanical devices and cables,

Mechanical vibrations (vibration) in machines, Abnormal operation of ignition circuits,

voltage spikes,

Punctures in cables and other electromechanical devices due to high voltage,

Malfunctions in electronic cards, devices and computers,

Power losses, punctures and explosions in power capacitors,

Trips in compensation fuses,

Unreasonable trips in breakers and switches,

Deterioration and abnormal operation of relay signals,

Energy losses

Harmonic filters are connected in series to the capacitors in the compensation system in order to eliminate these faults that occur in the facilities due to harmonic distortions. Particular attention should be paid to the selection of filters and capacitors in the filter compensation systems to be installed in order to correct harmonic distortions. The design of harmonic filters is made according to factors such as resonance frequency (mostly 134, 189, 210 Hz), capacitor power and capacitor voltage. A higher voltage is output from the harmonic filters compared to the mains voltage. Considering that the voltage value is higher than normal especially in organized industrial zones during the night, pay attention to the high voltage values of the capacitors to be installed in the system.
