Active Harmonic Filters: The Smart Way to Fix Harmonic Distortion Harmonic distortion is one of those hidden issues that can quietly wreak havoc on your electrical system. It’s responsible for things like overheated transformers, motor failures, and unexpected equipment shutdowns. If your facility uses a lot of variable-speed drives or other nonlinear loads, chances are you’ve s...
In today’s increasingly digital and power-electronic-driven world, understanding power quality parameters is essential—especially for engineers, technicians, and facility managers. One such important metric is THDi, or Total Harmonic Distortion of current. But what exactly is THDi, and how does it occur in electrical systems? What is THDi? THDi stands for Total Harmonic D...
What is Intelligent Tuning Integrated Capacitor ? In today’s low-voltage power distribution systems, improving energy efficiency and ensuring power quality are more important than ever. That’s where the Intelligent Tuning Integrated Capacitor comes into play. What Is an Intelligent Tuning Integrated Capacitor? The Intelligent Tuning Integrated Capacitor is a modern power compensation s...
Power Quality: Why It Matters and How YT Electric Provides Solutions What Is Power Quality, and Why Should We Care? In 2001, a Silicon Valley manufacturing company lost over $3 million in a single day due to a power outage that halted production.¹ Today, nearly 20% of the world’s electricity is wasted due to inefficiencies in power transmission and distributio...
The combination of a Static VAR Generator (SVG) and Thyristor-Switched Capacitor (TSC) creates a high-performance hybrid reactive power compensation system. This setup leverages the fast dynamic response of the SVG with the cost-effective bulk compensation capability of TSC. How SVG + TSC Works SVG (Static VAR Generator) Uses a voltage-source converter (VSC) with IGBT...
What is "HT sensing" in reactive power compensation? In a typical HT sensing and low-compensation scheme: HT sensing: The system samples voltage and current on the high-voltage side (e.g., 10kV) using CTs and PTs. Low-side compensation: The actual compensation—either reactive power support (SVG/capacitors) or harmonic filtering (AHF)—is implemented on the low-voltage side (e.g., 400V)....
Source-Grid-Load-Storage (SGLS) is a novel coordinated operational model for energy and power systems. It aims to build a flexible, efficient, and clean modern power system by integrating energy production, transmission, consumption, and storage. This concept represents a key solution to challenges such as large-scale renewable energy integration and dynamic power supply-demand balance amid t...
