Answer Posted / mohit kochhar
if LT applied to HT motor then motor winding will burn out.
because motor current is inversely propotional to voltage.
i f applied less voltage the motor current will increase.
e.g.
1500 kw motor supply voltage 6.6 kV current 155 A.
if applied 415 V then current is around 2000A .
