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

Why are some relay circuts designed to have the ct current flow through the neutral instead of the phase wire, such as in some diff relays?
