Answer / shiva
for any application selection depends on local distribution
(sub station ) transmission ,secondary voltage and finally
depends only on demand KVA of u r plant.

Answer / anuya
Basic & most important factor is transformer capacity which
can be derived by calculating all connected loads at
downstream. It will give the KVA rating.
Primary-secondary voltage ratio & vector group.
Environmental conditions like temp, etc. Application
Indoor/outdoor.
Cooling type requirement will deside the Xmer will be Oil
cooled or dry type unit.
Impedance of the Xmer.
Load type.

Answer / prabhu gnanasekaran
11 KV transformer or anyother transformer the calculation
of the transformer is done only as per the loads connected
in it(Continious load,stand by load and Auxillary load). No
of motors connected to it,KW rating of the mator, Total
line current of all motors.
If it is 11 KV the your primary side of the transformer is
11 KV thats all. Due to this 11 KV the line current
calcultation will change in the factor of system voltage
level in Line current calculation of the motor.

Why CT secondary should not be kept open?
Is there a possibility to use such a treshold voltage for the NMOS part of a CMOS circuit that during the switching it will start conducting only after the PMOS part will be already closed, by this eliminating the leakedge current? Please note, I'm not asking about the well bias in standby mode, but about the "antileakedge" measures during normal operation.
