Answer Posted / yogesh
in star-delta starter the starting current is reduced . Its about 1.5 to 3 times the full load . in DOL starter, it will be 6 to 7 times . Its because the starting current taken is just the one single phase current(R or B or Y)( phase current = line current) . thats why star-delta is used in HT motors .

i have a 4 Mva transformer 34.5 kv / 480-277 v and i used 2 parallel 3200 amp bus duct for the secondary feeder using 3 ply of bus bar ( 3/8" x 5" ) as a common where the flexible link terminated and 6300 amps breaker for the main, the lower bus duct reaches 70 degrees and the upper bus duct reaches 55 degrees when i used thermal scanner. why the temperature is not balance when the load reaches 3600 amps.
