In a three phase transformer(delta/star connected)when i
touch one end of the bulb in any one phase and other end to
earth..will the bulb glow or not..if not why?..i'm touching
the bulb in star connected side...

Answer / jagjeet
If it is distribution transformer and having 440 line to
line voltage , definately bulb should glow because the
bulb has been connected via earth i.e. 220 volts ( Phase &
Earth)

Answer / arockia doss
Bulb will glow.
Since, The req. voltage for the bulb will be coming from
the phase.
The neutral will be coming from the Earth.
Becuase, In the star connected trf. the neutral will be
earthed & So that, the bulb will glow.
Thanks ...

Answer / sachin rana
bulb will be glow if transformer is properly earthed i.e body as well as neutral

In a circuit a capacitor (paper capacitor ) was burned due to over voltage in this case can we replace that type cappacitor with other tye capacitor ?
What is the source of dependent source ?
What does Bode plot tell you?
why the motor running in delta connection ? it can be in star?
What is servo Motor? What's the advantages of this motor over Induction motor?
for selection of transformer we will considering 5 to 6 times of starting current of higher rating motor connected to secondary side. according to process wise we will start the motors gradually suppose if we will start 15 to 20 motors at a time wat will happen?
We are designer please help me calculate the size of 11kv cables from step up transformer to M.V panel, total load is 5 mega watt distance 900 feet (used aluminum type cables) please provided formula for calculate the cable with example.
pf of synchronius motor is unity, is it axact(=one) value. ?
Why do we perform an open-circuit test and short-circuit test on the transformer?
Why colled 440V to 3-phase supply.
please write motor, transformer, Generator setting, fault level calculation of Tr.etc
