NICER installations
General
NICER systems are fully automatically controlled, reactor-based reactive current compensations equipped with impregnated, harmonic-resistant capacitors of the H series.Nicer systems are used in grids with heavy harmonic distortion as well as generally where the service life is meant to be a few decades.
