Active Harmonic Correction Units(3 Products)
EATON

• AHCUs use advanced algorithms and sensors to continuously measure the current and voltage in the electrical system and identify the harmonic distortions present.
• With this measurement data, these devices calculate the precise phase and amplitude of the harmonic frequency.
• They then generate a compensating current that is precisely out of phase with the harmonic distortion and inject it into the electrical system.
• This process cancels out the entire spectrum of these distortions at the point of connection, resulting in improved power quality and equipment downtime.

Q. What are harmonic distortions?

A. Harmonic distortions are the deviation from pure sine waves caused by non-linear loads, including electronic equipment and variable frequency drives, causing issues like low power quality, reduced efficiency and equipment damage.

Q. What are passive filters?

A. Passive filters are composed of capacitors, inductors and / or resistors. They are designed to mitigate harmonic distortion caused by non-linear loads of VFDs or other electrical equipment. They filter out harmonic frequencies while allowing the fundamental frequency to pass through.

Q. What is a NEMA 1 enclosure?

A. Eaton active harmonic correction units are typically housed in NEMA enclosures to protect these devices from environmental factors like dust, water and oil.
