The WCOMP compensation units are the ideal choice when sensitive components must be installed outdoors.

Medium voltage components and control are installed in a stainless steel station building to protect them from inclement weather. This system type is often used as central compensation, e.g., of wind farms, as tele command blocking filter for grid link-up or as harmonic filter.

The housing dimensions vary from 1.8 to 7 meters in length and the maximum power is approx. 7 Mvar (10 kV). As with the R-, E-, and SCOMP series, the WCOMP also comes in three versions: WCOMP-F as fixed step with external actuation and without own switching device, WCOMP-E as externally controlled unit with integrated contactor, and WCOMP-A as automatically controlled system with integrated control and monitoring functions.

In addition, four standard reactors versions are available for this series: LINR (inrush current limiting reactor), 7 % (189 Hz), tele command blocking filter application or as filter for several harmonics.

In addition to the standard solutions, the WCOMP system is ideal for customized projects and modifications.
