Power up to 125 kVar

STPF panels are designed for 400V 50Hz networks and assembled with 440V nominal voltage capacitors; this ensures a high life even under continuous operating conditions with supply voltages exceeding 400V.

They are particularly suitable for power factor correction of cabin transformers.

Capacitors used in STPF panels are characterized by a high allowable overcurrent so as to guarantee their correct operation even in presence of harmonics.
