HGA 5% Active Harmonic Filter
The HarmonicGuard® Active (HGA) filter is an elite system-applied harmonic filter that minimizes harmonics to less than 5% total demand distortion (TDD) at the point of common coupling. The HGA monitors the load current and reacts to changes immediately. By injecting a counter-current, the active filter cancels out harmonics and synchronizes the current and voltage waveforms while improving power factor to near unity. One HGA filter can handle multiple non-linear, harmonic-generating loads.
Additionally, the HGA meets the demanding requirements of IEEE- 519-2014. Offering top of the line performance and mitigation, the HGA provides a lower cost and a smaller footprint than a comparable 18-pulse VFD or active front end drive.
A large, built-in 65k color touchscreen HMI display with LED backlight is included, along with communication options including Modbus RTU over RS485, EtherNet/IP, Modbus TCP/IP, BACNet/IP and DeviceNet.
Maximized Harmonic Mitigation in a Minimized Space
TCI now manufactures the largest active harmonic filter in a single standalone enclosure, made in the USA. One 700 Amp HarmonicGuard Active (HGA) filter can correct harmonics for an entire system in excess of 2,000 HP of VFD load. The new 350 Amp size offers the highest harmonic current capacity to fit within a 30” MCC section.

Sizing an Active Filter
Sizing an active filter has many factors, including transformer size, amount of linear and non-linear load, and impedance in your drives.
We understand sizing an Active filter can be difficult, which is why TCI created the HarmonicGuard Solution Center. It’s a completely free harmonic estimator software that enables users to size filtering solutions to meet harmonic calculations and power factor requirements.
The HarmonicGuard Solution Center is a web-based software, no download necessary.
