what is the difference between delta-delta, delta-star
transformer???
Answers were Sorted based on User's Feedback
Delta - de;ta transfomer is used at Gnerating station or a
receiving station for Change of Voltage , generally it is
used where the Voltage is high & Current is low.
where Delta star is a distribution kind of transfoemr where
from secondary star neutral is taken as a return path .
this configuration is used for Step down voltage phenomina

Answer / raj
delta delta transformer is used in generating systems and
transmission systems because voltage is major
consideration(voltage is stepped up to above 11 or 33kv i.e
220 or 440kv) and delta star transformer is a distribution
transformer(stepped down to 11kv or 440v) because current is
major consideration, in distribution systems we need a
neutral, so the neutral point is taken from star connection.

Hi frnds :) plz tell me that i have 100 KVA 3 phase generator so by thumb rule 100*1.4 = 144 amps and generaly we can operate at 80% load...so it will 144*0.8 =112 amps.... so now i m confused about single phase load.....if we use that generator only for single phase the that 112 amps is total single phase load or i can give 112 amps at red 112 amps at yellow and 112 amps at blue.... i mean that total single phase load that 100 KVA generator will take is 112+112+112=336 amp ??
