Understanding the Principles of Active Harmonic Filters (AHF) Active Harmonic Filters (AHF) are devices used to improve power quality. They reduce harmonic distortions and compensate for reactive power in electrical systems. The main idea behind AHF is to detect and counteract unwanted harmonic currents and reactive power. This helps make the power system more efficient and stable. Let&rsqu...
The Definition of Active Harmonic Filters (AHF) An Active Harmonic Filter (AHF) is an important device that improves power quality. Its main jobs are to reduce harmonic distortion in power systems and to adjust reactive power as needed. The AHF connects to the grid in parallel and performs real-time detection of harmonic components in the grid. A power converter creates a compensation current. Thi...
An Active Harmonic Filter (AHF) is a dynamic power quality management device. It based on power electronics technology, primarily designed to eliminate harmonic currents and compensate reactive power in electrical systems. Its core operation revolves around real-time detection, calculation, and dynamic compensation of harmonic distortions. So what situation do we need this equipment? Metallurgy In...
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...
