Power quality issues are a common occurrence in power systems. One of the most frequent issues is the voltage sag, which occurs when the voltage level drops below the normal operating voltage level for a short period. This can be caused by a fault in the system or sudden demand. Voltage swells occur when the voltage level exceeds the normal operating voltage level for a short period, which can cause damage to equipment.
Another common issue is harmonics, which is the presence of frequencies in the power system that are not part of the fundamental frequency. Harmonics can cause overheating in equipment and reduce its lifespan. Other disturbances that can affect power quality include transients, interruptions, and noise.
It is crucial to identify and address power quality issues promptly to prevent equipment failure, reduce downtime, and improve system performance. Power quality monitoring and analysis can help identify the causes of power quality issues, and the implementation of effective power quality solutions can mitigate their impact.
