For current production activities, high harmonics are a problem that almost all factories encounter during operation. It damages high-tech electrical equipment and disrupts production processes.
The hot development of grid-connected renewable energy projects as well as the massive growth of semiconductor devices have been making the impact of harmonics on the power system increasingly serious.
Harmful effects of Harmonics on the system:
High-order harmonics cause huge economic losses because today harmonics are not only found in factories but also the telecommunications industry, airport infrastructure, and data centers… all encounter harmonics. It directly affects the quality of the power source, causing the main production line to fail or stop production:
- Harmonics cause the cable to overheat, damaging the insulation.
- Reduces engine life, causes engine overheating, and makes a loud noise when operating.
- CB overload, overheating, and causing transformer explosion (while the amount of electricity used is still less than the norm).
- Circuit breakers, circuit breakers, and fuses can be affected for unknown reasons.
- Harmonics cause serious harm to capacitor banks by damaging the dielectric, bulging capacitors, reducing capacitor life, and even causing abnormal capacitor explosions.
- Causes interference affecting telecommunications equipment, automation systems such as PLC, Role,…
- Measuring devices are not working correctly.
- Waste of energy…
