Answer / ajit singh

as in delta Iph =Iline/1.732.so current in each phase will
be less resulting into less power consumption and losses.

Answer / nanda

We require good starting
Torque, So in Delta mode
it results good starting
torque than star mode

Answer / vinamra

low rating motor are direct delta connected because,in a
delta connection,motor torque is high than star connection.

Answer / nur.asidik

because almost load driven by motor is low power such as pump, so it safe to use delta starting

Answer / kumar

because there is no need for extra neutral connection and
the current consumption is less compared to star connection
and also initial current and torque is high.

Answer / shyam

in delta connection there is no ground like in star
connection.so it is easy to locate the armature or rotor at
the center of the stator of induction motor
