What types of metrics do power quality studies focus on?

Power quality studies primarily focus on performance and reliability metrics because these aspects are crucial for ensuring the stability and efficiency of electrical systems. Performance metrics include parameters such as voltage levels, frequency stability, and waveform distortion, which directly affect the operation of electrical equipment and the quality of power delivered to consumers. Reliability metrics assess the consistency and uptime of power supply, making sure that there are minimal interruptions and issues in the system.

The significance of focusing on these metrics lies in their impact on system performance; for instance, poor power quality can lead to equipment malfunctions or failures, increased operational costs, and safety hazards. Understanding these factors is essential for engineers and operators to maintain a robust power system, identify issues proactively, and implement solutions to enhance the overall power quality for end-users. Thus, the emphasis on performance and reliability metrics is foundational for effective power quality assessments and solutions.
