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...
Active Harmonic Filters (AHFs) are widely used in buildings to mitigate harmonic distortion caused by non-linear loads, ensuring power quality, energy efficiency, and compliance with standards like IEEE 519 and IEC 61000-3-6. Here are key applications of AHFs in buildings: 1. Office Buildings & Commercial Complexes Loads: LED lighting, VFDs (HVAC systems), elevators, UPS systems...
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...
From data centers in Frankfurt to EV charging stations in Southeast Asia, Active Harmonic Filters (AHFs) are rapidly becoming the gold standard for solving one of the most overlooked yet costly problems in industrial power systems—harmonics. Modern electrical loads such as variable frequency drives, inverters, and switching power supplies generate non-linear current waveforms, resulting in h...
Why Capacitors Are the Preferred Choice for Reactive Power Compensation When it comes to low-voltage reactive power compensation, the conversation usually narrows down to two options: capacitor banks and Static Var Generators. Ask around, and you’ll likely hear one common reason why capacitors remain popular:“They’re cheaper.” That’s true—but the real answer goe...
In Poland, reactive power management is governed by grid codes and regulations set by the Transmission System Operator (PSE - Polskie Sieci Elektroenergetyczne) and Distribution System Operators (DSOs). The policies aim to ensure grid stability, minimize losses, and maintain efficient power flow. 1. Reactive Power Requirements in Poland A. General Power Factor (PF) Standards St...
