Technical Reference
電力品質に関する技術情報
A structured library of power quality references, technical guides, and engineering tools — organized by topic for working engineers at all levels.
01
PQ の基礎
Power quality problems are easier to solve when you have a solid grasp of the underlying phenomena. This section covers the foundational concepts — definitions, disturbance categories, grounding principles, and electromagnetic compatibility basics — that apply across all industrial and utility environments.
Whether you are new to the field or need a structured reference, this is the right starting point before moving into more specialized topics.

高調波
Harmonics remain the most common and most misunderstood power quality problem in modern industrial installations. This section covers harmonic generation mechanisms, propagation on distribution networks, effects on motors and capacitor banks, resonance conditions, and mitigation using passive and active filter technologies.
Content is aligned with both IEC and IEEE standards frameworks and draws on utility-side experience — a perspective that differs from what you typically find in plant-floor literature.

基準 & EMC
Navigating the standards landscape is a prerequisite for any serious power quality work. This section consolidates references to the key IEC and IEEE power quality standards, EMC requirements for commercial and automotive applications, and international voltage and frequency norms.
Use this as your regulatory and compliance reference base — the documents and links here are the ones that actually show up in engineering practice, not just in textbooks.

Resources
Supporting material that complements the main technical sections — manufacturer references, periodicals, conference papers, and specialized topics that do not fit neatly into a single category.
A useful secondary reference when you need to go beyond the core content or look for external sources and industry contacts.
