Active Harmonic Filter

Schneider Active Harmonic Filters are:

  • A complete solution for harmonic filtering that meets every harmonic standard around the world.
  • Can be operated as a displacement power factor correction and load balancing device independent of or in conjunction with harmonic mitigation.

Technical data:

  • Network voltage: 208-480 VAC, up to 15 kV with custom transformers
  • Frequency: 50/60 Hz +/- 3 Hz
  • Harmonic compensation: H2 to H50, discrete spectrum cancellation; global or selectable
  • Ultra fast response at < 2 cycles
  • Ambient temperature: 0� to 40�C, derate 2% per degree C up to 50�C
  • Contamination levels (IEC 60721-3-3)
  • Altitude: 0 to 1000m (3300ft) above sea level - over 1000m derate 1% for each additional 100m
  • Product standards: UL, cUL, CSA, ABS, C-Tick, CE marked models available
  • Humidity: up to 95%, non condensing
  • Corrective Capability: < 5% TDD(I) & to near unity displacement power factor
  • HMI Display: Touchpad display with graphics
  • Enclosure: N1, UL Type 12, IP30, IP54, CH (Chassis)
  • Communication: 4 dry (voltage free) contacts to monitor status from remote location; Modbus TCP/IP or Ethernet IP.

Benefits:

  • Flexible and scalable
  • Easy sizing and independent of system impedance
  • Simple selection spreadsheet - no need for harmonic studies
  • Simple installation and ease of expansion
  • Peace of mind:
    • Achieves compliance with any harmonic standard anywhere around the world when sized correctly
    • Compatible with generator sources, UPS sources
    • Ensures energy efficiency by optimizing transformer and cable capacities;
    • reduces utility power factor penalties; and saves the cost of generation and transmission of reactive and harmonic current (non active currents)
    • Maximises up time when used for harmonic and/or power factor correction.

Applications:

  • Anywhere nonlinear loads are present:
  • Stop voltage sags and flicker due to load current fluctuations (VAR compensation)
