What kind of effects that provides to the power lines due to the harmonics? Please consider those harmonics are generated through electronic equipments?
Thanks in advance.
Thanks in advance.

Eranda said:Yp. I'm familiar with the power factor. I found that harmonics are generated through electronic devices; mostly due to SMPS. That switching purpose generates harmonics since the supply is not continuously provided.
As you meant the power factor, some of the power factor correction capacitor banks cause to this harmonics. As far as I know the Impedance of the p.f correction capacitor is inversely proportional to the frequency & Impedance of the source is directly proportional to the frequency. If the p.f correction capacitor is not specifically designed for these conditions, harmonics generates.
Am I missing something here?
Powerline harmonics are high-frequency disturbances or variations in the normal sine wave of an alternating current (AC) power supply. These harmonics are caused by the presence of non-linear loads, such as electronic devices, on the power grid.
Powerline harmonics can cause a variety of issues in electrical systems, including increased energy consumption, reduced efficiency, and overheating of equipment. They can also lead to interference with sensitive electronic devices, such as computers and medical equipment.
There is currently no concrete evidence to suggest that powerline harmonics have direct negative effects on human health. However, some studies have shown a possible correlation between exposure to high levels of harmonics and symptoms such as headaches, fatigue, and sleep disturbances.
The most effective way to reduce powerline harmonics is to limit the use of non-linear loads and ensure proper grounding and shielding of electrical systems. Additionally, installing harmonic filters and using power factor correction devices can help mitigate the effects of harmonics.
Yes, many countries have regulations in place to limit the amount of harmonics that can be introduced into the power grid. These regulations often include standards for equipment and limits on harmonic distortion levels. Compliance with these regulations is important for maintaining a stable and efficient power supply.
