which elements of a power system


1) generating  station  

2) load center


~ This includes a prime mover, the equipment needed to operate it, an exciter, a step-up transformer, a circuit breaker, and so on.  

~ The load center has consumers consuming electric power such as factory, shop, water supply, hospital, cinema etc.

~  The generating station and load center are connected by transmission line, substation and distribution line.

~  Above modern power supply system  Will system jelly is not easy.

~  In particular, there is a link between the generating station and the load center.

~   The voltage around the power ll kV is generated through the generator.

~  Normally this voltage is 132 kv. 220 & V or 400 kV.

~ Two or three long distance transmission lines are run in different areas. This is called high voltage

~  Each line has a receiving station, where the voltage is usually stepped down to 66 KV.

~ after send the voltage next station and step down to 11kv because some voltage drop the each station. 

 ~ There are 60 kv lines from the receiving station!

~ Total four types of lime 

     1) primary transmission line

    2) secondary transmission line

    3) primary distribution line

    4) secondary distribution line

~ This is called secondary transmission.

~ The end of the line is held in place.

~  66 KV voltage is converted to 11 kV with the help of transformer in substation,

~ 11kv voltage is converted to 240 v with the help  of stepdown transformer.

~ 240v line run home , shop and etc for power supply  

 ~Some KV feeders are transported to different areas.

~ because the need of high voltage supply power system for example, mall, showroom, hospital, building, complex etc.....

 ~ At the end of the feeder is a distribution transformer, which is placed on the pole.

~  11 kv is stepped down to 415 V through this transformer. 

~ 415 V lines run through various streets.  From this LT Consumer is supplied with single phase or three phase supply.

~ This is called low voltage or secondary distribution
