BRIEFLY ABOUT HARMONICS

HARMONIC GENERATION SOURCES

Considering the ever-increasing development of linear loads and their consumption in industrial and domestic equipment causes harmonics to be considered as one of the major challenges in electricity production and Consumption.

For instance, regarding to this type of loads, power electronic devices, home computers, low-consumption lamps, electric motors equipped with variable frequency drive (VFD), switched mode power supply, gas lamps, DC motors, types of diode, electric arc furnaces, … can be mentioned.

HARMONIC CONSTRUCTION

Harmonics have a sinusoidal waveform whose frequency is an integer multiples of the main wave frequency. Problems with this occurrence begin when they are aggregated with the main waveform and brings the waveform out of the sinusoidal state at the main frequency. This also affects the waveform amplitude and causes large fluctuations in its effective moment value.

SOME OF THE EFFECTS DUE TO THE PRESENCE OF HARMONICS

• Overheating of wires due to overloading caused by harmonics
• Lights flicker caused by harmonics in lighting lamps
• Overheating and shortening life expectancy of lighting lamps
• Overheating and shortening life expectancy of electrical motors caused by creation of left lateral component
• Fuses and relays failure
• Arising issues in UPS
• Failure of power factor correction capacitors

WHAT IS HARMONIC FILTER AND HOW IT CAN BE USED?

In regard to the  harms caused by  harmonics as well as their unwanted generation, Rahshad Electric Company manufactures harmonic filter based on the available skill and  experience. As shown in the pictures, this device can be easily installed in all types of buildings, and it only needs to connect its plug to one of the existing sockets in the building. As the device begins to operate, the harmonics that cause problems will be removed and the equipment will continue to operate safely.

The harmonic filters produced by this company are offered with a 1-year replacement warranty.
