Medium Voltage Soft Starters: HRVS-TX


Ratings: Up to 30MW, 15kV
The HRVS-TX transformer soft starter eliminates high inrush currents that
cause nuisance tripping and prevent the damaging effects on transformer windings.

HRVS-TX Information

A unique solution for large transformer high inrush current problems

HRVS-TX Application

The HRVS-TX is the ideal soft-starting solution for medium transformers. The sophisticated TSR-6 transformer protection and control relay eliminates high magnetizing inrush currents that can cause tripping and dynamic shock to the transformer windings.
