HT motors operates on high voltage ( 6.6 or 11KV). IF we
make delta connections than voltage experianced by windings
will be line voltage, which will require more insulation of
winding. In star connection voltage experinced by each
winding is phase voltage hence less insulation is required.
This is the reason HT motors always wound in star
connection.
