Ht Line Diagram

In power engineering a single line diagram sld also sometimes called one line diagram is a simplified notation for representing a three phase power system.

Ht line diagram. This over simplified analysis of a single line diagram gives you an idea of the kind of story such diagrams tell about electrical system connections and equipment. Basics 3 4 16 kv bus 1 line. Single line diagrams sld a single line diagram shows the disposition of equipment in a substation or network in a simplified manner using internationally accepted symbols to represent various items of equipment such as transformers circuit breakers and disconnectors generally with a single line being used to represent three phase connections. The one line diagram has its largest application in power flow studies electrical elements such as circuit breakers transformers capacitors bus bars and conductors are shown by standardized schematic symbols.

Themes can be color coded based on etap defaults voltage level area ground earthing. The rated voltage of lightning arresters shall be 9 kv rms. Basics 6 7 2 kv 3 line diagram. Set different themes for individual one line diagrams.

0 page 45 ht 01. Figure 12 h t diagram for water the quality of the mixture at any point in the liquid vapor region can be found using the same relationship as shown for the p h diagram. Just keep in mind that although some single line diagrams may appear overwhelming by virtue of their size and the wide variety of equipment represented they can all be analyzed using the same step by step method. Voltage rating for la.

Single line diagram of 11kv substation 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. Basics 8 aov elementary block diagram. X h h f h fg rev.

11kv 415v over head line s specification and installation rec. This will be applicable to the effectively earthed 11 kv systems co efficient of earth not exceeding 80 percent as per is. The user can also add contouring as an option. 11kv lightning arrester is.

This functionality allows the user to place a user configurable color map behind the one line diagram. Basics 4 600 v 1 line. As a layman view sld is nothing but consisting of various components of the electrical system like transformer dg panels consisting of ht breaker lt breaker ct pt. Basics 9 4 16 kv pump schematic.

It is used to transmit power at very small distances and uses thicker conductors. Basics 5 480 v mcc 1 line. Basics 10 480 v pump schematic. As shown in figure 12 operation outside the saturation lines results in a subcooled liquid or superheated steam.
