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.

why do we put a transformer on soak before loading it
A TRANSFORMER 440/400V,DELTA/STAR CONNECTED.THE NEUTRAL CONNECTED WITH GROUND CABLE THAT IS DIRECTLY CONNECTED TO THE PANEL,FROM PANEL IT IS CONNECTED EARTH PIT.IS IT RIGHT? IF IT IS RIGHT LEAKAGE CURRENT AFFECTED.SECONDATY IS PROTECTED WITH EARTH LEAKAGE RELAY.
Draw the wave shape of armature current in a generator subjected to a sudden three phase short- circuit at its terminals. Define various reactance of generator from this wave shape.

upto how many load can v connect to stabilizer which is used for tv
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.
