What is substation and classification of substation?

The operating voltage based substations are high voltage, extra high voltage, and ultra-high voltage substations. The importance based substations are grid and town substations. The design based substations are indoor, outdoor, foundation mounted and pole mounted substations.

What are the classification of the substation according to the design?

4 Classification based on application

Primary Grid Substation – Created at suitable load centre along primary transmission lines. Secondary Substation – Along secondary transmission line. Distribution Substation – Created where the transmission line voltage is step down to supply voltage.

What are the classification of indoor and outdoor substation?

What is an indoor and outdoor substation? The substation which installs for low voltage requirements inside the building construction is called an indoor substation. The substation which installs for high voltage requirements outside the building construction is called an outdoor substation.

What are primary and secondary substations?

The primary substations are the interconnection between high voltage and medium voltage. The secondary substations are the interconnection between medium and low voltage. SEA produces HV/MV, MV/MV, MV/LV transformers, both liquid immersed and dry type.

What is substation and its components?

The electrical power can be transmitted from the units of generation to distribution using various electrical substation components namely isolator, bus bar, power transformer, etc are connected together in the substation.

What are the types of transformer substations?

What is transformer substation – Types of transformer substation
  • Table of content:
  • a. Intermediate transformer station.
  • b. Distribution substation.
  • Pole mounted substation.
  • Gantry transformer substation.
  • a. Outdoor transformer station.
  • b. Indoor transformer station.

What are the 3 types of power distribution?

There are three basic types of distribution system designs: Radial, Loop, or Network. As you might expect, you can use combinations of these three systems, and this is frequently done. The Radial distribution system is the cheapest to build, and is widely used in sparsely populated areas.

What’s a primary substation?

Primary. Substations. Primary substation are points in our power system where power is transformed from 33kV to 11kV or 6.6kV. These can be found all around our network and can be inside buildings or outside. The use of extra high voltage allows us to distribute electricity in large quantities and safely.

What is a primary sub station?

Primary substations are infrastructures dedicated to the interconnection between high voltage and medium voltage in the electrical system and can be built in different environmental contexts whenever energy demand makes a primary substation needed.

What is substation design?

The design of the substations mostly contains The Transformers, Circuit Switches, Breakers, Transmitters, and the Capacitors. The transformers carry out the task of stepping down the high voltage electricity to lower voltage electricity which is suitable enough to send through the distribution wires.

How the distribution systems are classified?

According to scheme of connection, the distribution system may be classified as (a) radial system (b) ring main system (c) inter-connected system. meters.

What are the factors to be considered while designing and building an electrical substation?

Distribution substation design must be a combination of reliability and quality of the power supply, safety, economics, maintainability, simplicity of operation, and functionality. Safety of life and preservation of property are the two most important factors in the design of the substation.

Which of the following is a type of substation according to service requirement?

According to the service requirement, sub-stations may be classified into : (i) Transformer sub-stations. Those sub-stations which change the voltage level of electric supply are called transformer sub-stations. These sub-stations receive power at some voltage and deliver it at some other voltage.

What are the 3 types of distribution system?

There are three basic types of distribution system designs: Radial, Loop, or Network.

What are the 3 types of power systems?

The electrical power system consists of three major components: generation, a high voltage transmission grid, and a distribution system.

What are the types of distribution?

The three types of distribution channels are wholesalers, retailers, and direct-to-consumer sales.

What is feeder in substation?

In electrical engineering, a feeder line is a type of transmission line. In addition Feeders are the power lines through which electricity is transmitted in power systems. Feeder transmits power from Generating station or substation to the distribution points.

What is DC 3 wire system?

Three Wire DC Distribution Systems: It consists of two outer wires and a middle or neutral wire which is earthed at the substation. Availability of two voltages in a 3-wire system is preferred over the 2-wire system for d.c. distribution.
