why ht motor connection in star

Answer Posted / avdhesh

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.

Is there a possibility to use such a treshold voltage for the NMOS part of a CMOS circuit that during the switching it will start conducting only after the PMOS part will be already closed, by this eliminating the leakedge current? Please note, I'm not asking about the well bias in standby mode, but about the "antileakedge" measures during normal operation.
