As site conditions vary with time and differ from one area to another, this configuration requires the transformer rectifier to be constructed according to the specific criteria of the protection to be achieved.

IPSI designs and manufactures various types and models of transformers rectifier, in particular two large families of AIR or OIL cooled systems with manual or servo adjustment.

Components are calculated and sized in accordance with the severe operating conditions as well as the usable life and requirements of the structure to be protected.

We offer a wide variety of options that can be built into our transformer rectifiers, e.g. alarm, measurement, control, and remote transmission features.
