Hello!    

If you've ever tried to swat a fly, you know that it can be tricky because the little bugger is wired to move this way and that - unpredictably.  You have to constantly adjust your swing in real-time.

Dynamic Correction of Every Harmonic Order - Today's Reality
The SLAC National Accelerator Laboratory, at Menlo Park, California is a research facility of the highest caliber - used by scientists from many countries and home to Nobel Prize-winning research.  Imagine the heartbreak when that facility experienced the loss of sensitive data due to disk arrays that crashed because of Harmonics.

Boris Llinets, P.E., electrical engineer assigned to the data center, researched many solutions - looking at both passive and active harmonic filters.  He decided upon StacoSine, an active harmonic filter from Staco Energy, because of the wide range of harmonics present from his servers, disc arrays and switches in the facility.  Aside from the simpler installation and cost-efficiency that this solution provided, what really sold him was the automatic correction of the multiple harmonic orders that were present at his facility.

StacoSine active harmonic filters use power electronic technology to monitor the non-linear loads and dynamically correct every harmonic order from the 3rd through the 51st.

Through an injection and cancellation process, the sine wave is restored and distortion is reduced to less than 5% total harmonic distortion (THD), meeting the stringent IEEE 519 Standard. By injecting a compensating current into the load, the waveform is restored, dramatically reducing distortion to below 5% THD. Power is moved from the AC source to the DC electronic platform, then back to the AC. This occurs at a very rapid rate, allowing for cancellation of the high frequency output current, followed by determining the precise value of the injected load current. The power electronics platform continuously adapts to rapid load conditions, yet maintains a small physical footprint.

Since installation, Llinets has  seen no problems from harmonic distortion.

StacoSine®
Active Harmonic Filter
Staco Energy Products introduces a new open chassis product line of StacoSine® active harmonic filters.  

StacoSine Active Harmonic Filter

The open chassis assembly allows a wide range of original equipment manufacturers, systems integrators and panel builders to incorporate the StacoSine® within their final equipment configurations.  This can include motor control centers, switchgear/switchboards, automation controls, and other electrical power distribution apparatus.   The active filter can be mounted in a 20" deep enclosure, up through 300 amps.

Active Harmonic Filters dynamically cancel problematic harmonics from the 3rd to the 51st order - allowing more efficient use of electricity.  The active filter measures the harmonics generated from a nonlinear load and cancels them with a newly generated, opposite phase shifted harmonic current of the same amplitude (AC/DC/AC).   StacoSine® active harmonic filters are ideal for use with variable frequency drive systems, pumps/HVAC, water and wastewater treatment plants, off-shore oil platforms, on-site and emergency power generation, three-phase UPS, datacenters, process industries and general manufacturing environments.
