Answer / manish

the difference is in switch yard voltage level does not
changed only voltage level is maintained & in substation
voltage level can b increased & decreased as well.

Answer / mahesh sali

The function of substation is to stepping up or down the
voltages as per requirements , There r so many substation
classification has been decided by IEC and IS ,

The function of Switchyards is to delivered the generated
power from power plant at desired voltage level to the
nearest grid ,

Answer / kk(krishnakanth)

Substation and switchyard both are different and these two
are inter connectors between the generating station and
transmission and distribution,

switchyard is the inter connector between
generation and transmission, and same voltage is mentained
in switchyard.

substation is the inter connector between
transmission and distribution systems, and various voltage
levels are mentained in substation.

Answer / amit kumar chaudhary

The application of substation is to stepping up or down the
voltages as per requirements , There r so many substation
classification has been decided by IEC and IS ,Transmission
substation, distribution substation etc.

The application of Switchyards is to deliver the generated
power from power plant at desired voltage level to the
nearest grid or transmission line.

Answer / kand

Substation is doing stepping up /down the voltage level as
requirement of load.Its just used to connect the load
between two different voltage level.(transformers +
switches used)

Switchyard is also called as power distribution network.
(group of switches inclu CB,DS & ES etc..)Its distribute
the power one to many network with the same operating
voltage.No limitation of voltage level

Answer / engineered

when we define substation, we call it 220/33kV, 100MVA
substation.

& when we define switchyard, we call it 220kV switchyard,
33kV switchyard.

Switchyards are generally in open yards, while substation
can be indoor as well as outdoor also.

Answer / nivash

Substation is a combination of switch yard and control
room.switch yard is a place where HT equipments (from 66-
765kV) such as EHV current transformers, CVTs,
CBs,isolators, power transformers etc are erected.

There is no existence of only switchyard any where i.e
swithc yard become meaning less without control room.

Answer / shubham batham

A switchyard is where the power is maintained at same level without change of voltage after generating transformer the power is feed to the switchyard with the help of conductor bar.
A substation is that where the voltage level is maintain both of condition step up or step down as per requirement400/220/132/11 kV substation

Answer / abdullah javed

Substation is the part of the power system where voltage level is changed and switching is being done.

Moreover, Switch yard is the area where switching is being done and it is the intermediate substation between generation and distribution.

Answer / alok

A switch yard connects one part of power system to another without changing the voltage level while a substation have a Transformer to change the voltage Level(it have almost all the equipment same as switch yards)
