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.

In the era of Industry 4.0, harmonic pollution caused by nonlinear loads has become a critical challenge for power system stability. Choosing the right harmonic filter is essential for protecting equipment lifespan and improving energy efficiency. As a technological leader in power electronics, Intone Power provides an in-depth analysis of Active Harmonic Filters (AHF) and Passive Harmonic Filters (PHF), helping you make informed decisions.

Active Harmonic Filters (AHF) are essential for improving power quality in modern power systems. Harmonics can cause equipment overheating, energy waste, and even machinery failures. This guide explains how to install and use AHFs step by step, using simple language and practical tips.

As industries increasingly rely on advanced electrical systems, harmonic distortion poses a significant threat to equipment efficiency, safety, and grid stability. The IEEE 519-2014 standard serves as the gold standard for managing harmonic distortion in power systems. At Intone Power, we empower businesses to achieve compliance and optimize energy performance. In this guide, we break down the key updates, measurement methods, and actionable strategies to meet IEEE 519-2014 requirements.

Power quality is like a health check for your electrical system. It measures if your machines get clean, stable power to run smoothly. Bad power quality causes problems like flickering lights, sudden shutdowns, or damaged equipment. For factories, this can mean lost production time and costly repairs.

In modern power systems, maintaining stable voltage levels and minimizing harmonic distortions are critical for industrial, commercial, and renewable energy applications. At SHANGHAI Intonepower, we specialize in high voltage side compensation solutions that enhance grid reliability, reduce energy losses, and comply with global power quality standards. Our innovative technologies, including Active Harmonic Filters (AHF) and Dynamic Reactive Power Compensation Systems, deliver unmatched efficiency and precision.

Even with complete compensation of the low-voltage side reactive power, the transformer itself generated reactive power, causing the high-voltage side power factor to remain below the required level.
To address the high-voltage side reactive power generated by the transformer, the on-site high-voltage side power quality was measured.
