What are Reactive Power and Reactive Power compensation? Reactive power is a key part of AC electrical systems—it’s the energy that flows back and forth between the power source and the load. Unlike active power, which does the actual work like powering lights or running machines, reactive power doesn’t directly get used up. But it plays a crucial role in keeping voltage levels s...
Power Factor Correction Methods Efficient energy management has become a cornerstone of modern industries and commercial facilities. Among the various strategies to optimize energy usage, Power Factor Correction (PFC) stands out as a critical approach for reducing energy losses, improving power quality, and minimizing costs. Reactive power compensation methods play a vital role in achieving...

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...

Discover YT Electric’s globally compliant APF systems. Why Dual Compliance Matters for APF in Global Projects? Modern power quality challenges require activ...
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...
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...
