Analysis of 3 Different Power Factor Correction Solutions: Capacitors, SVG, and AHF In today’s industrial and commercial environments, ensuring power quality is more than just good practice—it’s a necessity. Poor power quality can lead to equipment malfunctions, increased utility costs, and downtime. One major aspect of power quality is the power factor—a measure of ho...
1. Current Transformer (CT) A Current Transformer is an instrument transformer used to measure alternating current (AC) by stepping down high currents to a lower, measurable value. Key Functions: Current Measurement: Steps down high primary current (e.g., 1000A) to a standardized secondary current (e.g., 5A or 1A) for meters and relays. Isolation: Provides galvanic isolation be...

This article conducts a comprehensive analysis of the impacts, costs, and advanced equipment solutions related to power quality in China, drawing insight...
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...
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...
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...
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...
