The main consequences of harmonics

Harmonics appear more and more frequently in our daily life. The more frequent to find a high presence of harmonics usually in hospitals, universities, government centers, shopping centers, laboratories, heavy industries, radio, TV, broadcasting, food industry, hotel and casino, highly automated industry, water treatment plants.The most common harmonic generating devices including: switching power supplies, welders,Ups,old frequency converter with thyristor power converter technology, motor drives, converters with controlled rectifiers, DC controller for DC drives, Induction ovens.
The main consequences of harmonics as below:
1.Overheating and vibrations with premature aging of all parts, with short and medium term effects on life expectancy.
2.Faults on power electronics equipment.
3.Damage to printed circuit board components.
4.Electric motor overload.
5.Premature aging capacitors and damage due to resonance.
6.Power factor reduction.
7.Overload of the neutral wire.
8.Electromagnetic influence.
9.Measurement errors on energy meters.
10.MCCB and contactor interruption fault.
11.Incorrect tripping of switch.
Active harmonic filters are energy quality devices that dynamically supply a controlled current that has the same amplitude as the harmonic current, which is injected in opposition to the harmonics on the network. This will eliminate the harmonic current in the electrical system. As a result, the current supplied by the power source will remain sinusoidal as the harmonics will cancel each other out and harmonic distortion will be reduced to very low value.
Active filters can be installed anywhere on a network and offer many features:
1.Eliminate all harmonic currents up to 50th order from non-linear loads.
2.Compensate the reactive power and correct the power factor.
3.Compensate for flicker caused by reactive power.
Noker Electric active power filter adopts the most advanced three-level technology, with the characteristics of small size, high power density, stable and reliable performance, which is favored by customers.It can simply do harmonic governance, reactive power compensation, also can do harmonic governance + reactive power compensation, harmonic frequency from 3 to 50 harmonic, can maximize the optimization of your grid quality.
