Medium Voltage Inrush Current Limiter: 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.

A Unique Solution for Large Transformer High Inrush Current Problems

The HRVS-TX is a unique solution for limiting inrush current to Medium Voltage Transformers. The specialized algorithm in the TSR-6 Protection Relay ensures the complete elimination of the large magnetizing inrush current and dynamic shock to the transformer windings and to the electrical network.
