Answer / lakshmi

power is generated at11kv and multiples of 11 bcz of form
factor i.e., for sinusoidal is 1.11.

Answer / pratap

please send me ans

Answer / vijayakrishnan

may be increased greater than 11kv insulation of winding also increased & maintenance also tough.
step up transformer used for reduced cost of conductor

Answer / subbu

normally the genaration station genarates only 6.6kv it is
step up and sen to near substation then we r using
6.6kv/11kv it for avoiding lossesi.e eddy current.then we
step up/down as per load on the feeder

Answer / amardeep sah

Reduce losses eddy current and hystersis and tough maintanance and so 11kv used for sted up and step down in transmission line

Answer / yash sharma

remember it - "higher voltage is beneficial for transmission not for The generation"

sine wave has form factor of 1.11
so 1.11*10000=11 kv
1.11*20000=22 kv and so on

Answer / thingujam

1) 11kv is a reliable and conventional generating voltage.
2) Multiple of 11KV is a conventional multiplying factor

Answer / dkverma67

AS insulation of alternator winding is comparatively easy & economical at 11KV.
Voltage rating is always multiple of 1.1 or 11 due to form factor. EMF induced in alternator is E(max.) value. The average value of induced EMF =Emaximum x 1.11.Here 1.11 is farm factor.

What effect does a very low impedance have on the Voltage regulation? On the short-circuit current?
