What is electrical transmission substation?

What is electrical transmission substation?

A transmission substation connects two or more transmission lines. The simplest case is where all transmission lines have the same voltage. In such cases, substation contains high-voltage switches that allow lines to be connected or isolated for fault clearance or maintenance.

What is transformer substation definition?

an electric substation that steps up or steps down the voltage of an AC power system, and also distributes electric power. A transformer substation usually has one or two power transformers, distribution equipment, control and protective devices, and auxiliary equipment. …

What does 220 kv substation mean?

220kV substation equipment. This is accomplished by suitable apparatus called Substation. For example, generation voltage (11KV or 6.6KV) at the power station is stepped up to high voltage (say 220KV or 132KV) for transmission of electric power. The assembly of apparatus (e.g. transformer etc.)

What is a collector substation?

A collector substation works with projects that collect energy from many small energy sources. While the collector substation shares a resemblance to the distributor substation, its power flow works in the opposite direction, collecting energy and feeding a transmission grid.

What are the types of substation?

Types of Sub Stations

  • Step-up Type Substation. This type of substation gets the power supply from a near producing facility.
  • Customer Substation.
  • System Stations.
  • Distribution Type Substation.
  • Step-down Type Substation.
  • Underground Distribution Substation.
  • Switchyard.
  • 11kv Substation.

What are the different types of transformer substation?

Why 11kV 22kv 33KV 66KV?

Due to the form factor=1.11, so output voltage must be multiply of form factor, so we get 11,22,33. In case of a sinusoidal wave, the form factor is approximately 1.11. The reason is something historical.

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 is substation explain classification of substation?

The substation is the medium of transferring the power from generating unit to the consumer end. It consists different types of equipment like transformer, generator, power cable which helps in the power transmission. The substation which generates the power is known as the generating substation.

What is the difference between 33kV and 11kV?

The 11kV lines are used in residential areas and is what feeds the local transformers, which then distributes power to the buildings in the area. 33kV lines on the other hand involve much higher voltages and are used to distribute power from one small sub-station to another.

How is a substation different from a transmission line?

Subtransmission voltages are usually between 26 kV and 69 kV. i) A step-up substation connects the power plant to the transmission lines. ii) A step-down substation connects the transmission lines to sub-transmission or distribution lines. iii) A distribution substation connects subtransmission lines to the distribution lines.

What is the voltage of a step up substation?

An electrical power generating plans typically generate voltages between 2.3kV and 33kV. Step up substations contain high voltage transformers that boost the generator output voltage to a value between 115kV and 765kV, and provide power outputs in the thousands of kilovolt-amperes (kVA) and higher.

What is the layout of a distribution substation?

DISTRIBUTION SUBSTATION LAYOUT 1. Single source, single feeder substation The one-line diagram of a single-source, single-feeder substation with the minimum equipment used. A bypass switch is provided so service can continue during circuit breaker maintenance. The probability of a fault during circuit breaker maintenance

Which is a subsidiary station of the transmission system?

Electrical Substation An electrical substationis a subsidiary station of an electricity generation, transmission and distribution system where voltage is transformed from high to low or the reverse using transformers.
