Active filters for reactive power compensation AHF 100A

Active Harmonic Filters – Comprehensive Installation Protection

Active filters, such as AHF 100A, are advanced devices designed to improve the quality of energy in electrical installations. Their main task is to compensate for reactive power and reduce harmonic currents, which negatively affect the operation of devices and increase energy costs. This solution is used both in industrial and commercial installations, where there is a large number of non-linear loads, such as computers, switch-mode power supplies, LED lighting or inverters.

Active filters offer a number of advantages compared to traditional compensation methods. They react quickly to changes in load, effectively suppress harmonics up to high orders (even 50th) and allow compensation for both inductive and capacitive reactive power. Additionally, 4-wire models help reduce current in the neutral conductor, which translates to lower energy losses and network load.

Versatile Application and Flexibility

AHF 100A filters are available in 3-phase (3P) and 4-phase (3P+N) versions, allowing them to be adapted to different installation configurations. The ability to operate in different modes – reactive power compensation, harmonic reduction or priority filtering – ensures optimal performance depending on the specifics of the load. These devices can also be connected in parallel, allowing the system to be expanded and adapted to changing needs.

Key Features and Benefits:

• Effective reactive power compensation: Improvement of the power factor (cos φ) and reduction of energy losses.
• Harmonic reduction: Reducing interference in the electrical network and protecting sensitive electronic devices.
• Load balancing: Reduction of current in the neutral conductor in 4-wire installations.
• Fast response: Dynamic compensation of reactive power and harmonic filtering even with rapidly changing loads.
• Configuration flexibility: Ability to operate in different modes and expand the system by connecting filters in parallel.
• High efficiency: Achieving energy efficiency at over 97%, which translates into energy savings.
• Protections: Built-in thermal and overload protection ensures safe operation of the device.
• MODBUS communication: Allows remote monitoring and configuration of the filter using a computer.

Sinexcel AHF 100A active filters are an investment in the reliability and energy efficiency of the electrical installation, which translates into savings in operating costs and improved power quality for connected devices. They are particularly recommended for use in public buildings, office buildings, server rooms and small industrial plants with a large number of non-linear loads.
