Answer / vijay singh

LT motor work on 440 volt
HT motor work on 3.3 kv or more

Answer / himmat

DEPENDING ON AVAILABILITY OF SUPPLY VOLTAGE THE MOTORS CAN BE CLASSIFIED AS
FOLLOWS: -
1 AS PER AMERICAN/EUROPEAN PRACTICE: -
A) LT RANGE MOTORS – 230 VOLTS, 415 VOLTS
B) MEDIUM VOLTAGE RANG- 690 VOLTS TO 3300 VOLTS
C) HT RANGE MOTORS – 6600 VOLTS AND 11000 VOLTS.
2) AS PER INDIAN PRACTICE: -
LT RANGE MEANS 230 VOLTS, 415VOLTS AND 690 VOLTS
AND HT MEANS 3300, 6600 AND 11000 VOLTS RANGE.

Answer / siva krishna

LT Motor works below 415 volts
HT Motor works above 415 volts

Answer / prashanth

As per Indian Electrical Practice motor voltage level defines LT or HT

LT Motor - voltage level 0 - 680 V
HT Motor - Voltage level 690- 11000 V
EHT Motor - voltage level 33000 V and above

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.

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

Answer / amol mohite

Motor operating on 6.6 kv is called HT motor and all motors below 6.6 kv is called as LT motor

Answer / muhammad numan

According to Suadi Aramco Standards
Motors working with voltage 3.3KV and above are HT motors

Answer / manish

LT motors works with below 700 volts and HT motors is
working on or above 700 volts.
