Question { Pfizer, 16936 }

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

In Blower application, starting current will be more than
normal until it gets full speed due to dampers, hence
better idea to use OLR with starting current delay time and
running current delay time setting. so that while starting
time this OLR waits for some time delay even starting
current is more than normal and trip.
