why do we prefer a 3-phase delta connected load rather than
star connected?
Answers were Sorted based on User's Feedback
In star speed of motor is very low with low amp.
and in delta motor running with its normal rated speed with
rated amp.
So generally for motor starting purpose star used and
afterthat its change over to delta

Answer / nithi
for a same power rating the current in delta connected load
is 1.732 times lesser than the star connected load (heat
loss is less) &also if one phase get opened the other two
phases will serve the load i.e.good stability.but in safety
point of view, star connected load is better than delta
load.because earthing can be done without the help of
earthing transformer.

Dear Subhash
Yes speed of motor will remain same in star and delta both

Can any body tell me what is use of END OF LINE RESISTOR in fire alaram circuit?
why voltage drop if we have connected 230 v ac suplly through diode to bulbe we found haft ie 110 voltage drop why it is
any application of back emf
How many no. of earthing pits required for commisioning a new 320KVC DG Set????How????
Please clarify 1. Icw: rated short circuit working withstand capacity 2. Icu: Rated ultimate breaking capacity 3. Ics: Rated service short circut withstand capacity 4. other specification of ACB
Is ground earthing required for neutral conductor of a prime mover ie DG set?
at work we have a 3 phase motor but on testing one phase isnt getting a reading. it runs 24 hours a day all week. stops and starts well no noise or heating. the phase isnt down to earth.is it just a bad meter reading or not? phases one and three came up with a resistance reading of 0.4 but phase 2 couldnt get anything shows up as open circuit.
we change the speed of the synchronous motor by incresing or decreasing a rotor resistance
how can we run the induction motor at 9000 rpm ,by keeping frequency constant??
Does Rheostat can use for power factor correction?
What is the relay function?
Dear all, i completed M.E(Power Electronics & Drives) 2011 passed out having 78% so i need job in core side but i don't know how can i receive the calls from electrical companies and i uploaded my CV in naukri, times jobs etc.. In that iam not recieved any mails from good companies so give me best procedure plzzzzzzzzzzzzzzzzzzzzzzzz..... Thanks, K.Linga Reddy Email-id:-lingareddykmthm@gmail.com Ph no:-08015402078
