Block diagram 11kv substation. Key diagram 11kv400v i the 3 phase 3 wire 11 kv line is tapped and brought to the gang operating switch installed near the sub station. Single line diagram of 11kv substation substation provides the energy supply for the local area in which the line is located. The input for a distribution substation is typically at least two transmission or subtransmission lines. A substation is a part of an electrical generation transmission and distribution system where voltage is transformed from high to low or low to high or many other important functions.

Key diagram of 11kv400v indoor substation. Distribution substation a distribution substation transfers power from the transmission system to the distribution system of an area. 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.

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. Dol starter control and power wiring diagram.

The key diagram of this sub station can be explained as under. Central station where power is generated by 3 phase alternators. The 3 phase 3 wire 11 kv line is tapped and brought to the gang operating switch installed near the sub station. Switch consists of isolators connected in each phase of the 3 phase line.

2511 shows the key diagram of substation of a typical 11 kv400 v indoor sub station. Distribution voltages are typically medium voltage between 24 and 33 kv depending on the size of the area served and the practices of the local utility. Figure 1 single line diagram of transmission and distribution network. There is numerous electrical substation components like outgoing and incoming circuitry each of which having its circuit breakers isolators transformers and busbar system etc for the smooth functioning of the system.
