why ht motor connection in star

Answer / avdhesh
HT motors operates on high voltage ( 6.6 or 11KV). IF we
make delta connections than voltage experianced by windings
will be line voltage, which will require more insulation of
winding. In star connection voltage experinced by each
winding is phase voltage hence less insulation is required.
This is the reason HT motors always wound in star
connection.

Answer / narayanaswamy
I am of the opinion that star connection of HT motor is done to have better operation of protective gear

Answer / pankaj gajare
Because HT motor having large starting current so that if
your connection will be in star then your current will be
root three so its automatically reduce.
its star delta principle...in star connection current will
root three times reduce.

Answer / jameel
the ht motor connection in star because it is easy and
cheaper than delta connection in high voltage and star
delta connection not used in this system .
and the best question here why the ht capacitor of power
factor connection star not delta although the delta
connection is more economecal than star. we need in star
three times farad(reactive power) of ccapacitor than delta
but we connection star not delta because the same reason in
ht motor.
but the ht transformer some times it is necssary to
conection the primary or the secondary or both delta
accrding to the requirment of network.

Answer / priti
in star connected sysytms...u can provide it with a
neutral..so that in case of faults the fault current will
flow through the neural nd hence preventing shocks!!

WHAT IS OLTC OF TRANSFORMER? WHERE IS ITS USED EITHER ON PRIMARY OR SECONDARY SIDE OF TRANSFORMER?
is it value of power factor is more than unit. whats effects in the source supply

What are the protection used for alternator,transformers.
Can we use shunt trip coil instead of trip coil with protection relay for protection?
i want to ask that as everybody knows that in star connection on star point is called neutral. my question is that why on that poin called neutral. what is the reason behind it. what is the logic behind it. i heared somewhere that on this point all phases current become zero thats why. if this answer is right then prove why on that point is current become zero. if this answer is not right then tell me the right answer. post ur answer here or on my mail address. m.ikram786@yahoo.com m.ikram555@gmail.com. thanks.
what is a relay?
what is the difference between delta delta and star delta connection transformer? why we use delta delta transformer since it need earthing transformer for grounding?
