What are the classification of substations?

The different types of substations mainly include Step-up Type Substation, Step-down Transformer, Distribution, Underground Distribution, Switchyard, Customer Substation, and System Station.

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 are the three main parts of a substation?

There are three main types of substation: transmission, distribution, and collector.
  • Transmission. A transmission substation connects transmission lines, generally when all the lines concerned have the same level of voltage. …
  • Distribution. …
  • Collector.

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.

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 are 2 types of transformers?

Commonly used transformer type, depending upon voltage they are classified as:
  • Step-up Transformer: They are used between the power generator and the power grid. …
  • Step down Transformer: These transformers are used to convert high voltage primary supply to low voltage secondary output.

What is the function of substation?

The purpose of a substation is to ‘step down’ high voltage electricity from the transmission system to lower voltage electricity so it can be easily supplied to homes and businesses in the area through lower voltage distribution lines.

What are the classification of transformer?

These are classified as power transformer, protection transformer, measuring transformer and distribution transformer.

What is primary and secondary in electrical?

Typical primary voltages include 7,200 volts single phase and 12,500 volts three phase. Secondary lines, or secondaries, are located lower down on utility poles, usually below transformers. Typical secondary voltages are between 120 volts to 480 volts.

What is the difference between primary and secondary distribution system?

A primary distribution is an initial sale of securities on the secondary market, such as in the case of an IPO. By contrast, a secondary distribution refers to the sale of existing securities among buyers and sellers on the secondary market.

What is secondary sub station?

A Compact Secondary Substation (CSS) is a type tested and arc tested assembly comprising an enclosure containing medium voltage (MV) switchgear, distribution transformers, low voltage (LV) switchboards, connections and auxiliary equipment to supply LV energy from MV systems.

What is primary and secondary equipment?

The primary system consists of the primary equipment and its interconnected electrical circuits. Secondary equipment is equipment that controls, regulates, protects, and monitors primary equipment. The system of secondary equipment and its interconnected electrical circuits is called a secondary system.

Why 11kV is used in distribution system?

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.

What is the difference between feeder and distributor?

The distributor is a conductor which distributes the electrical power in particular area. A feeder has no tapping on it. It has a number of tapping on me through which the electrical power is actually reached to consumer premises. Current through it always remains same.
