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.

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

How feedback transformer works to feedback power in Slip Power Recovery System
A group of machines (wind turbines) connected with 33KV feeder and each machines are having individual VCB. The 33KV feeder connected with 110KV/33KV substation. The 33KV feeder tripped by over current at Substation and fault recorded at Substation as OC-R&Y phase. Same time the group of machines VCB tripped by over voltage, the fault recorded voltage was above 66KV by numerical Under/Over voltage relay. While grid drop time, this much of voltage hike is possible?
