Answer / pragathi

The assembly of apparatus used to change some
characteristics (eg., voltage, ac to dc conversion,
frequency, power factor, switching operation etc.,)of
electric supply is called a sub-station.

Answer / h r jadhav

in power system sub station is playing very vital role for
handeling electrical juise. it is a place where power
transformers or power distribution transformers are
installed and being uesed for transforming one voltage
level into another desired system voltage level of
electrical energy in a energy efficient way.and called as
sub station.

Answer / shoaib9786

when a generating station produces power, the voltage is
around 11kv... This voltage is stepped up to 220kv for
transmission purpose and then at a receiving station it is
stepped down to 66kv and then transmitted to a substation
where the voltage is further droppped to around 6.6kv for
distribution purpose. So a substation is a place where
power is transmitted from receiving station and stepped
down.

hope that answers

1. If we apply dc supply to the primary winding of transformer it will be burnt out. similarly dc supply is given to field winding of syn. motor and armature winding of dc motor, they are safe. (Remember both windings inductive nature) what is the reason behind that?
