Harmonic Filters
Crohm builds the resistor element of harmonic-filter assemblies used to reduce harmonic distortion and improve power quality on variable-frequency-drive and power-factor-correction systems. Filter resistors are engineered to the specified ohmic value, continuous power rating and duty for each installation.
Typical applications
- Detuned and tuned harmonic-filter banks
- Power-factor-correction capacitor damping
- Variable-frequency-drive input filtering
- Renewable and UPS power conditioning
Construction
- Series CG grid or CE edgewound elements sized to duty
- Double-insulated frames with stainless terminals
- Indoor or outdoor enclosures to NEMA ratings
- Optional thermal protection and interconnections
