What types of metrics do power quality studies focus on?

Power quality studies primarily focus on performance and reliability metrics because these metrics are essential for assessing the quality of electrical power delivered to consumers. Performance metrics might include voltage stability, frequency variation, and harmonic distortion, all of which impact how well electrical devices operate. Reliability metrics relate to the consistency and dependability of power supply, including metrics like outage frequency and duration.

These metrics are crucial for ensuring that the electrical system operates efficiently and effectively, minimizing disruptions and enhancing the overall reliability of power supply. Understanding and measuring these aspects help utilities, engineers, and stakeholders identify problem areas, implement corrective actions, and maintain compliance with established standards.

In contrast, cost metrics, safety compliance metrics, and aesthetic metrics do not directly address the technical performance or operational reliability of electrical systems. While those aspects are important in a broader context, they do not focus on the core issues of power quality that can significantly affect equipment performance and service reliability.
