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

When capacitor bank connect on line. It's draw some current but it's current not increase of main line ammeter. Why?

In Dyn11 power transformer if any one of the 3 phases connected to earth in star connected side then please explain effect of the current flow in delta connected side of transformer.(In this case if one phase is shorted to ground in star connected side then we observe the current flow in two phases only not three phases in delta connected primary side. Please explain why it is so?)

an amazing situation was faced when an alive distribution panel with 415 volts and carrying almost 200Amps has become short and this metal cubical showing 220 volts against neutral and earth. to redress any confusion i checked the panel with help of single 200watts test lamp which also glowing with max.intensity b/w neutral & metal body of DB. amazing situation is that i hold the DB firmly more than once with necked foot means without insulated shoes but not received any electrical shock. whereas our all running gen sets neutral points also proper grounded and this short DB was completely earthed , this is beyond my understanding . any body explain how is it possible . our running gen set neutral also grounded firmly
