HRVS-DN TX

HRVS-TX Eliminating Transformer Inrush Current for low and medium voltage transformers

Solcon’s latest development in the field of Medium Voltage Inrush current limiting technology.

The HRVS-TX is the ideal soft-starting solution for medium and low voltage transformers. The sophisticated TSR-6 transformer protection and control relay ensures the elimination of the magnetizing inrush current, thus, eliminates nuisance tripping as well as dynamic shock to the transformer windings. The starter can be supplied as IP31-67, NEMA 1-6X with options such as Line and Bypass vacuum contactors or circuit breakers, disconnect switches, main and control protection fuses, transformer protection relay, etc.
