What Are TDD and THD? — A Comprehensive Explanation of Harmonic Distortion Indicators In power systems and power quality management, harmonic distortion is a crucial issue that cannot be ignored. Two key indicators used to measure harmonic distortion are THD (Total Harmonic Distortion) and TDD (Total Demand Distortion). These terms are commonly referenced in technical specifications a...
Access to electricity is expanding globally, but challenges persist. While more people are gaining connections to power grids, issues such as frequent outages and poor power quality remain widespread, particularly in developing regions. Poor power quality, often characterized by voltage fluctuations and inadequate electrical performance, affects millions of users. It hampers their ability to use e...
Clean Power Solutions for Modern Office Towers The power networks in today’s skyscrapers and large office buildings face increasingly complex challenges. From nonlinear loads like elevators, LED lighting, and IT systems to harmonic pollution affecting the power supply's quality, maintaining optimal power quality is critical. This blog explores how the YTPQC Active Harmonic Filters effectivel...
IEEE 519 Harmonic Distortion Limits: Guide to Compliance The IEEE 519-2022 standard, called Harmonic Control in Electric Power Systems, sets rules for designing electrical systems to reduce harmonic distortion. What Does the Standard Do? IEEE 519-2022 helps engineers manage harmonics in power systems. It covers both linear loads (like motors and regular light bulbs) and nonlinear loads...
