1. Veritas Control
  2. HRVS-TX



Medium Voltage Inrush Current Limiter
Up to 100MVA, 36kV

The HRVS-TX eliminates transformer inrush current for all types of Medium Voltage Transformers, up to 100
MVA at 36kV. It is the ideal current limiting solution for Medium Voltage Transformers. Its sophisticated control
ensures the elimination of the magnetizing inrush current, eliminating nuisance tripping as well as dynamic
shock to the transformer windings. The current limiter can be supplied as IP31-54 with options such as Line and
Bypass vacuum contactors and optional circuit breakers, disconnect switches, main and control protection
fuses and transformer protection relays.
