Low Voltage
Automatic Harmonic Filter Equipment
Specifications
Controllix Low Voltage Automatic Harmonic Filters are the definitive solution for facilities where non-linear loads fluctuate throughout the day. By combining high-end capacitors with precisely matched reactors, these units act as a “sink” for harmonic currents while simultaneously correcting the power factor. The automatic controller ensures that the system provides the exact amount of compensation needed at any given moment, preventing leading power factor conditions and protecting the system from resonance—even as VFD-driven equipment cycles on and off.
Medium Voltage
Harmonic Filter Banks
Specifications
Engineered for the most demanding electrical environments, Controllix Medium Voltage Harmonic Filter Banks are custom-tuned to solve specific site resonance issues. These banks are typically installed at the main plant bus or substation to clean the power for the entire facility. By using iron-core or air-core reactors specifically sized for the site’s harmonic profile, these banks provide bulk kVAR support while safely diverting harmonic energy to ground. This not only ensures compliance with utility-imposed IEEE 519 limits but also significantly extends the lifespan of high-value medium voltage transformers and switchgear.
Harmonic Filter Banks & Mitigation Solutions
A Harmonic Filter Bank is a specialized power quality system designed to eliminate harmonic distortion and provide reactive power compensation in electrical networks. Unlike standard capacitor banks, harmonic filters utilize iron-core or air-core reactors to “trap” specific harmonic frequencies (such as the 5th, 7th, or 11th) generated by non-linear loads like VFDs and LED lighting. Controllix harmonic filters prevent system resonance, reduce equipment overheating, and ensure facility compliance with IEEE 519 standards, protecting sensitive electronics and avoiding utility penalties.
Understanding the Need for Harmonic Filtering
In modern industrial environments, non-linear loads convert AC to DC, creating harmonic currents that distort the voltage waveform. Without proper filtering, these harmonics can cause:
- Nuisance Tripping: Circuit breakers and fuses failing without an apparent overload.
- Equipment Overheating: Excessive heat in transformers, motors, and neutral conductors.
- Capacitor Failure: Standard capacitor banks can resonate with harmonics, leading to catastrophic failure.
