Power quality assessment is about checking how clean and stable the electrical power is for the equipment that uses it. It looks at voltage level and stability, how often the electrical frequency stays within limits, and the shape of the voltage and current waveforms. The goal is to see if there are disturbances—like harmonics, voltage sags or swells, interruptions, flicker, and fast transient events—that exceed acceptable limits set by standards. By identifying those issues, the assessment points to what needs to be done to mitigate them, such as adding filters, voltage regulation, UPS backup, improved grounding, or other power conditioning measures. This helps ensure equipment operates reliably, avoids nuisance tripping, and stays compliant with relevant standards. It isn’t primarily about protecting inverter configurations, calculating how efficiently the system runs, or deciding when to schedule maintenance downtime.
