dilo Electrical substation high-voltage separating unit

Indoor substations with high voltage of 110-220 kV are usually built in densely populated areas in large cities. They bear large electrical distribution loads and have a constantly operator on duty, also they should have noise isolation protecting the local population from the noise generated by the transformers.

News Detail

  • Distribution Substations

    The unit substation is a relatively recent development. A unit substation is factory built and tested, then shipped in modules that are bolted together at the site. Unit substations usually contain high and low voltage disconnect switches, one or two three-phase transformers, low voltage breakers, high voltage fusing, bus work, and relays.

  • Classification of Electrical Substations on 5 Basis

    The main function of the electrical substation are to receive energy transmitted at high voltage from the generating substation, decrease the voltage to a value convenient for local distribution and provide facilities for switching. Depending on the purposes the electrical substations may be classified into various types. The types of electrical substations are explained below.

    Jun 15, 2018A few converter substations convert the high-voltage AC to high-voltage DC for the regional interconnections. The high-voltage transformers, particularly those of 345 kV and above, are critical to the proper functioning of the electric system. In the US HVTS there are about 2,100 transformers rated at 345 kV and above (DOE 2015).
