Outdoor medium and high voltage harmonic filters BSN

 
      C” type 2nd harmonics filter 46MVar/38,5kV            3rd harmonics filter 2x35MVar/42kV
 
Medium and high voltage harmonic filters are designed individually on customer's request.
The solutions are outdoor type, based on single-phase capacitors, which are connected in series and parallel in order to achieve desired power and voltage values.
Capacitor banks can be installed as fixed, automatic switched or automatic regulated, with or without reactors, on steel racks or on poles, in single- or three-phase execution.

"ELMA energia" company offers full range of installation services: beginning from project, through building and assembling works, ending on starting-up, commissioning and final tests.
