what is the deference between HT and LT motor. why its deferent use

WHAT IS DIFFERENT BETWEEN HT MOTOR AND LT MOTOR

HELLO,

THE DIFFERENCE BETWEEN HT AND LT MOTORS ARE :

FOR THE SAME POWER RATING THE SIZE OF THE LT MOTOR

IS MUCH BIGGER THAN HT MOTOR. But the insulation level in HT motor is

more straightener 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 greater than

100 Kw.that can be taken in LT if HT is not available there & space is

available.


IN SHORT :

LT Motor Worke Under 1KV & HT Motor Work Over The 1KV

LT Motor Required more current then HT Motor

GOOD LUCK

pls system lighting

what is difference between soft starter and derive ?

What is the difference between HT and LT motor

please tell me difference between LT motor and HP motor ?

Can a LT motor can be used in stead of HT motor?

dear member,

I difine below difference between HT & LT.

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.

THE RATING OF THE PROTECTING ELEMENTS FOR THE LT MOTOR IS MORE
WHEN COMPARED TO THE HT MOTOR AS LT MOTOR CARIES MORE CURRENT.

Dear friend for the same power rating the size of 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.


Best of luck........

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 3LT Motor works below 415 volts
HT Motor works above 415 volts 300, 6600 AND 11000 VOLTS RANGE.

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

Ht motors mean high tension wire current if availble and ur reqirement is more than100 hp in ht case mean low voltsmean 440 and under 100 hp

what is the major difference between HT and LT motors in specification vise ?

How is energy being saved in HT (High Tension/Voltage) motors? As we know power consumed by a motor is 1.732 x V x I x power factor. If we reduce the current by employing HT motor then on the same time we are increasing the voltage factor. Thus the product of voltage and current will remain same. Then how energy is being saved in HT motors? Please reply by giving some example or comparison

In Indian standard ht&Lt motor show me a perfect difference in on answer

LT motor is 230 volts to 415 volt and 690 volts
Ht motor 6.6 kv to 11kv
Lt motor is space cosum is less
Ht motor is spece cosum in high
Lt motor insulation stranth is low
Ht motor insulation stranth high
Lt motor product is pasta
Ht motor product is slow
