11KW Delta motor is taking about 44Amps in star and goes
upto 70Amps in delta and trips OFF. The rated current is
26Amps. Application is for the blower. The motor takes ( no
load without coupling impller ) only 2.5A and 5Amps in star
& delta starter test.Need to know why its taking high
current.

Answer Posted / gunasekaran
u r not explain proberly it is due to inrust current for
star phase voltage=VL/sqrt3
for delta phase voltage=line voltage so it is taking more
current than star.normally at stating motor taking 5to 6
six times of the full load current i think nothing wrong u
can incress the relay setting and then start the motor
