Active Power Filter ELEKTON-FSA for VSD on Rated Current from 630 up to 1600 A

Purpose and application

The Active Power Filter ELEKTON-FSA is intended for effective decrease of the higher harmonic components' level HHC of the VSD switchboard's 3-phase voltage supply and for reactive power compensation, which is load consumed.

The Filter ELEKTON-FSA is plugged between transformer substation and VSD switchboard's input. Special adjustments and regulations are not required.

The rated operating current of the Active Power Filter defines the consumed power of the higher harmonic components, which are generated to mains supply.

Functional capabilities

The higher harmonic components (HHС) increasing in power circuit is caused, first of all, by wide use of converting techniques. The Active Power Filters is the most effective way of elimination of the higher harmonic components.

The Active Power Filter represents the controlled current source connected in parallel with loading, generating the higher harmonic components. This controlled current source generates the same and the same size as a current loading but in an antiphase. So, a current of the first harmonic (50 Hz) consumes only by loading of a mains.

• Three-phase HHС compensation of current up to 40-th harmonic inclusively
• Low power losses (3 … 5 % from rated power of loading)
• The built-in electronic overload protection
• Port RS-485
• Controller ELEKTON-10.1
• Displaying on the controller of the following: harmonic components and voltage nonsinusoidality factor, supply current and load current loading
• History

* - maximum root-mean-square current of HHС.
** - maximum consumption current of Switchboard ELEKTON-05 in length modulation mode.
*** - under condition of input voltage (no VSD Switchboard involved) distortion coefficient being less than 2% while filter operates uder rated load.

Active Power Filter rated working current determines extreme suppressed power of HHС which are generated into main supply.
