The Accusine Power Correction System (PCS) actively injects current for harmonic filtering and power factor correction. Using reliable IGBT technology, Accusine PCS is able to cancel harmonics generated by non-linear (power-electronic) loads by injecting harmonic current of opposite polarity. Accusine installation will reduce harmonic levels for IEEE 519 compliance.
 |
Decreases harmonic related overheating of cables, switchgear and transformers |
|
Reduces downtime caused by nuisance thermal tripping of protective devices |
|
Increases electrical network reliability and reduces operating costs |
|
Corrects to the 50th harmonic |
|
Compensates entire network or specific loads depending on installation point |
Accusine PCS features a sub-cycle response time allowing for dynamic VAR injection to reduce voltage sags created by inductive load switching. In addition, Accusine PCS can inject peak current at two and a half times its rms current rating for one cycle. Accusine PCS can also operate in a dual mode where current is first injected to reduce hamonics and any excess current capacity is used to improve the power factor.
|
Independent phase compensation |
|
UL and CSA approved |
|
Parallel connection allows for easy retrofit and installation of multiple units for large networks |
|
Response to load fluctuations begins in 40 microseconds with 8 milliseconds for full response to step load changes |
|
50, 100 and 300 A models for 208–480 V. Other voltages available. |
A harmonic study is not required to select the size of the Accusine PCS installation. This is because when Accusine PCS is installed it becomes a lower impedance path for harmonics than the existing power supply. For sizing, please contact the Square D Power Quality Correction Group at (905) 678-6699. To expedite the product selection process, please have a single line diagram and/or details of the application including sizes of transformers, non-linear and linear loads, and any existing filters and capacitors.

Three CTs required for networks with line-neutral loads. Two remote current transformers required for three phase loads. For installations requiring parallel connection of multiple Accusine for increased correction capacity, special considerations may be required. Contact the Square D Power Quality Correction Group for details.
The AccuSine Sizing Spreadsheet, available on www.SquareD.com under Free Software and Online Tools, can be used to define the amount of corrective current to be provided by the AccuSine PCS.
