• The substation design process includes the following:
  • Civil - Structural design including earthworks,
  • drainage,
  • roads,
  • foundations,
  • bunds,
  • structures,
  • fencing and
  • buildings.

• Substation Types:
  • there are generally four types of substations
  • there are substations that are a combination of two or more types.
  • Step-up Transmission Substation.
  • Step-down Transmission Substation.
  • Distribution Substation.
  • Underground Distribution Substation.
  • Substation Functions.
  • Substation Equipment.

• A DC energy:
• While most devices and consumer electronics rely on AC energy for power,
• portable substations continue to operate on DC energy.
• DC supply has been widely used in substations and portable power applications for many years

• An 132 kV substation:
• A 132kv Grid Station is that part of power system where high voltage of 132kv is received,
• stepped down to 11kv and then given to different feeders that feed distribution lines.
• This whole process is carried out by different parts and equipment".

• An 11KV substation:
• DESIGN AND CONSTRUCTION OF 33/11 KV SUB STATION WITH SAFETY etc
• 11KV which is deliver by substation is directly given to the HT(high tension) consumer like industrial area.
• that line known as a primary distribution line.
• Electrical power from primary distribution line is deliver to the various station.
• its called distribution station

• An 220 33kV mean:
• 220/132/33 kV would be the rated voltages of a power transformer with an incoming 220kV supply
• and two secondary outputs of 132 kV and 33kV. This is calle.
• 60/90 MVA refers to two ratings of a power transformer depending on how it is cooled.

• Frish Air not only Cooling:
• Bathroom - Toilet, Basement
• Exhaust air solutions for multi-family houses
• Comfort ventilation for houses and living spaces
• Air purifiers for individual rooms
• Industry and commerce
• Special applications, e.g. potentially explosive areas
• Accessories and service parts
