Question { 10726 }

why a three phase transformer cant rotate like three phase motor

Answer

Because Transformer only transfer load from higher level to
lower level in technical can say Transformer can stepup and
step down the voltage. so, this is call static device not
moving device.Configuration of transformer is Dry type Oil
type for distribution of load with diffent cooling
process . Three phase motor has rorating field through
shaft of motor.Due to this cause transformer rating always
in ative load (KVA) not in Real Load (KW).and Motor has
name with real load and HP rating.

Question { UltraTech, 7687 }

for a 5hp motor to operate from 100kva generator ,what size
of cable required in sqmm.

Answer

5HP Motor are use as single phase on D.O.L or Star/Delta
connection as 3 phase. If you use single phase then total
load is 3.7kw so we can use 6mm sq cable .if you use in y/D
connection the required to use 4cx6 sq mm cable.

Question { DSC, 7782 }
