Features Of Compact Substation

  • Designed for indoor installation close to their point of use at the center of the major load consumers.
  • These transformers are combined with their primary and secondary switchgear and distribution boards into compact substations that are installed directly at their point of use.
  • This reduces construction requirements, cable costs, transmission losses and installation costs.
  • Transformer is fitted with three temperature sensors installed in the LV winding, and a solid-state tripping device with relay output.
  • It can be mounted on a roof top (for dry type transformer) where you want the power supply.
