what is the difference between LT & HT Motors..

Answer / rajpurohit

fOR THE SAME POWER RATING THE SIZE OF THE LT MOTOR IS MUCH
BIGGER THAN HT MOTOR. But the insulaton level in HT motor
is more strenghter than LT motor. the current is very high
in same rating LT motor so the rating of the protection
device will be higher than HT type motor.
so generally we have taken HT motor in bigger size like
geater than 100 Kw. that can be taken in LT if HT is not
available there & space is availabe.

Answer / subasis panda

LT RANGE MOTORS – 230 VOLTS, 415 VOLTS
HT RANGE MOTORS – 6600 VOLTS AND 11000 VOLTS.
The insulation level in HT motor
is more strengthener than LT motor. the current is very high
in same rating LT motor so the rating of the protection
device will be higher than HT type motor.

what is the difference between LT & HT Motors..

Answer / krishna tanuz

LT MOTOR IS HAVING THE RATING <200KW OF VOLTAGE 415V
HT MOTOR IS HAVING THE RATING <=200KW OF VOLTAGE 6600V,3300V,11000V
THE RATING OF THE PROTECTING ELEMENTS FOR THE LT MOTOR IS MORE
WHEN COMPARED TO THE HT MOTOR AS LT MOTOR CARIES MORE CURRENT

Is This Answer Correct ?    11 Yes 11 No
