Why is CT Selection the Core of AHF System Performance? The current transformer (CT), as the "sensing organ" of the active harmonic filter (AHF), directly affects the accuracy of harmonic detection and the dynamic response speed. If the CT is not properly selected, the following problems may occur: Failure of Harmonic Compensation: Low-frequency or high-frequency harmonics are missed in det...
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...
Think of our power grid like a giant Jenga tower. As we add more wind turbines and solar panels (the green blocks), the tower becomes wobblier. This happens because sunshine and wind change like mood swings. One minute your solar panels are pumping out power during a cloudless noon, the next they’re napping when a storm rolls in. This makes the entire electricity system feel like a weak Wi-F...
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...
