Active harmonic filters today are designed to calculate the amplitudes and phase angle of each harmonic order. the power devices are directed to produce a current of equal amplitude but opposite phase angle for specific harmonic orders. this limits the response to specific harmonic orders and may require up to two or more cycles (>33 milliseconds)it is a complete solution for harmonic filtering along with the improvement in power factor correction.

benefits:

• compatible with all types of harmonic producing loads
• compatible with future load changes
• simple selection online tool
• easy sizing and independent of system impedance
• simple installation and ease of expansion
• flexible parallel operation modes for multi-unit installations
• 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)

 

technical specification:

• free standing/wall mounted ul approved
• filtration from 2nd to 50th order harmonics
• can be interfaced with ethernet/web server
• 32 bit dsp technology
• touch screen display with multiple monitoring options.
• less than 3% losses.
