Non-linear loads distort current waveforms, resulting in poor power factor and higher demand charges. Our Harmonic Filter Chokes are optimized for detuned filter applications (typically 189 Hz/210 Hz/134 Hz), protecting capacitors from harmonic overload and allowing precise power factor correction without risk of resonance. This ensures long-term stability of capacitor banks and compliance with IEEE 519 and EN 61000-3-2 standards.
Voltage amplification due to resonance between power factor capacitors and system inductance can damage insulation and degrade sensitive equipment. By introducing high-frequency impedance, our chokes dampen resonance peaks and provide dielectric relief to system components. Core saturation is minimized even during transient overloads due to high-quality, low-loss magnetic materials with tightly controlled flux density limits.
Rapid load changes in variable frequency drives (VFDs), CNCs, and rectifier-based systems induce current surges and harmonic spikes. Harmonic Filter Chokes stabilize current flow through inductive smoothing and ensure system impedance remains within calculated thresholds. High thermal class windings and vacuum-impregnated coils ensure mechanical integrity under vibration and high-frequency thermal cycling.

Frigate designs chokes using low-loss magnetic cores with high linearity to maintain inductance across varying load currents. Finite Element Analysis (FEA) is used to simulate magnetic flux behavior under partial and full-load conditions. Core saturation is avoided by maintaining flux density below material thresholds. This ensures consistent harmonic filtering performance even under fluctuating non-linear loads.
Frigate selects thermal Class H or F insulation systems based on current rating and duty cycle. Windings are dimensioned for low AC resistance and optimized surface area for heat dissipation. Vacuum impregnation enhances thermal conductivity and mechanical rigidity. Temperature rise is verified using simulation and test data as per IEC 60076-6.
Frigate uses interleaved lamination stacks and tight coil clamping to reduce magnetic flux-induced vibrations. Coils are resin-encapsulated or vacuum varnished to dampen acoustic noise during high-frequency operation. Core joints are precision-machined to minimize magnetostriction effects. These practices ensure low audible noise, especially critical in commercial and sensitive industrial environments.
Frigate conducts routine and type tests in accordance with IEC 61558-2-20 and IEEE C57.110 standards. This includes inductance, impedance, high-voltage dielectric, temperature rise, and THDi attenuation tests. Harmonic filtering performance is verified using grid simulation setups. Each unit is also subjected to surge and insulation resistance testing before dispatch.
Yes, Frigate develops custom chokes for low-voltage and medium-voltage harmonic mitigation. High-voltage insulation systems and segmented winding designs are applied for dielectric strength and thermal management. Designs include air-gapped iron-core topologies for stable inductance under higher voltages. Each unit undergoes impulse and partial discharge testing as per voltage class.
