Lineator™ AUHF
The Lineator™ Advanced Universal Harmonic Filter (AUHF) is a passive harmonic filter originally developed to address variable frequency drive (VFD) harmonics across a variety of industries. As a trusted solution for managing modern power quality challenges, this system mitigates the negative effects of harmonics, improves the overall efficiency of your electrical distribution system, and guarantees compliance with international safety and operational standards.
Technical Overview
The Lineator™ AUHF utilizes a wide-spectrum passive design to deliver performance and reliability under real-world operating conditions.
- Guaranteed compliance with IEEE Std 519 to protect sensitive equipment and maintain a healthy power system.
- Passive filtration design that’s easy to install, configure, and maintain without complex power electronics.
- Full generator compatibility to eliminate the risk of system instability or power supply disruptions.
- Documented global reliability with over 100,000 individual units currently in service around the world.
- Reduced energy use and overall operating costs by converting distorted harmonic content into clean power.
- Configurable with optional accessories including DNV or Lloyds certification, integrated contactors, temperature switches, tin plating, coordinated surge protection, and the InSight™ power meter.
Typical Applications
The Lineator™ series is specified across mission-critical industries where managing the harmonics generated by three-phase, six-pulse rectifier loads is essential.
