dilo Electrical substation high-voltage deivces

Substations Types The main purposes for establishment of a substation are: Need for connecting a generator to the transmission system: We have already discussed that generators generate electricity at a low voltage mostly below 22 kV. But bulk quantity of power can be transmitted to very long distance only at high or extra high voltage.

  • Distribution Substations

    Distribution substation A distribution substation transfers power from the transmission system to the distribution system of an area. The input for a distribution substation is typically at least two transmission or subtransmission lines. Distribution voltages are typically medium voltage, between 2.4 and 33 kV depending on the size of the area served and the practices of the local utility.
