Actually it is consists of a feeder controlling room and a switching yard. All controlling such as line current each feeder, line and phase voltage for each feeder are measured by many Low Tension LT panel and High tension panel HT. Switch yard is the place where the actual equipment are working properly. This switching sub-station is mainly consists of two parts.

The main components are described below briefly:. This is a large place where switch gear components are paced according to the one line diagram which is provided by an experienced electrical engineer after electrical calculation. In Sub-Station, it is often desired to disconnect a part of the system for general maintenance and repairs. This is accomplished by an isolating switch or isolator.

If an isolator is opened carelessly, when carrying high current the resulting arc easily causes flashover to earth. Search for:. Premium Membership. More Information. Power substation guides, research papers and studies. An isolator is essentially a knife Switch and is design to often open a circuit under no loadin other words, isolator Switches are operate only when the line is which they are connected carry no load.

For example, consider that the isolator are connected on both side of a cut breaker, if the isolators are to be opened, the C. Related EEP's content with sponsored links.

Single Line Diagram of Substations. Pankaj Choudhary. Single Line Diagram of Substations Substations Electric power is produced at the power generating stations, which are generally located far away from the load centers.

High voltage transmission lines are used to transmit the electric power from the generating stations to the load centers. Between the power generating station and consumers a number of transformations and switching stations are required.

These are generally known as substations. Substations are important part of power system and form a link between generating stations, transmission systems and distribution systems. It is an assembly of electrical components such as bus-bars, switchgear apparatus, power transformers etc.

Their main functions are to receive power transmitted at high voltage from the generating stations and reduce the voltage to a value suitable for distribution.

Some substations provide facilities for switching operations of transmission lines, others are converting stations. Substations are provided with safety devices to disconnect equipment or circuit at the time of faults.

Substations are the convenient place for installing synchronous condensers for the purpose of improving power factor and it provide facilities for making measurements to monitor the operation of the various parts of the power system. The substations may be classified in according to service requirements and constructional features. According to service requirements it is classified in to transformer substations, switching substations and converting substations. They are used to transform power from one voltage level to another voltage level.

Transformer is the main component in such substations. Transformer substations are further classified into Step-up substations, Primary grid substations, Secondary substations and Distribution substations. Generating voltage of the order of 11kV needs to be stepped up to a primary transmission voltage level of the order of kV or kV.

Large consumers are supplied power at 11kV. Different connections are made between the various transmission lines. Some are used to change the frequency from higher to lower or vice versa for industry utilisations.

According to constructional features substations are classified into Indoor substations, Outdoor substations, Underground substations and Pole mounted substations. Single Line Diagram Any complex power system even though they are three phase circuits, can be represented by a single line diagram, showing various electrical components of power system and their interconnection.Substation provides the energy supply for the local area in which the line is located.

The main function of the substation is to collect the energy transmitted at high voltage from the generating station and then reduce the voltage to an appropriate value for local distribution and gives facilities for switching. The substation is of two types one is the simple switching type where the different connection between transmission line are made and the other is the converting stations which convert AC to DC or vice versa or convert frequency from higher to lower or lower to higher.

The substation has an additional function like they provide points where safety devices may be installed to disconnect equipment or circuit in the event of the fault. The synchronous condenser is placed at the end of the transmission line for improving the power factor and for measuring the operation at the various part of the power system. Street lighting, as well as the switching control for street lighting, can be installed in a substation. The single line diagram of an 11 KV substation is shown in the figure below.

The single line diagram makes the system easy and it provides the facilitates reading of the electrical supply and connection. Your email address will not be published. Save my name, email, and website in this browser for the next time I comment. Circuit Globe All about Electrical and Electronics.

CVT measures voltage and steeps down at V. A current transformer is connected in series with line which measure current and step down current at ratio for control panel. At both ends of transformer lightning arrester current transformer and switchgear equipment provided.

Transformer step downs voltage from KV to 33KV. Capacitor bank is connected to main bus of 11KV. There is no clarity in description and it gives no new information. A single line diagram would be better. Search for:. Premium Membership. More Information. Power substation guides, research papers and studies.
