What are different types of substations?
Substation Types: Although, 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.
What is the area required for 220 kV substation?
High Voltage Substation (HV Substation): Involving voltage between 11 kV and 66kV. Extra-High Voltage Substation (EHV Substation): Involving voltage between 132 kV and 400kV….Detailed Solution.
| Type of Substation | Area Required |
|---|---|
| 132 kV Substation | 10 acres |
| 220 kV Substation | 25 acres |
| 400 kV Substation | 50 acres |
How does a substation work?
Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. A substation may include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two different transmission voltages.
How many types of electrical substations are there?
These substations are classified into three types based on voltage level. High voltage substation serves voltage in range of 11 kV to 66 kV. Extra high voltage substation serves voltage in range of 132 kV to 400 kV. High voltage substation operates above 400 kV voltage range.
What is 11KV substation?
11 KV Substation. Pole-Mounted Sub-Station: 1. It is a distribution sub-station placed overhead on a pole. It is the cheapest form of substation as it does not involve any building work.
What do electricity substations do?
Substations range from small substations, dotted through communities, supplying electricity at mains voltage to hmes – we call them “final distribution substations” – to much bigger “transmission” or “grid” substations, usually outside urban areas.
What is a kV in electricity?
Definition of kilovolt : a unit of potential difference equal to 1000 volts.
What is a 400 220 kv substation?
400/220/132 KV substation. The first step towards the design of a 400/220/132 KV substation is to determine the load that the substation has to cater and develop it accordingly. The substation is responsible for catering bulk power to various load centres distributed all around through 220 KV and 132 KV substations.
