Question
what is the difference between LT and HT power supply?
 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
lt supply is in the range of voltage less than 1000volts.
HV supply are in kilovolts 6.6,11,33,66,132KV

Answer
# 3
LT means Low Tenson and voltage will be low and current
will be high.
HT means High Tenson and voltage 11kv to 33kv so Voltage
will be high and current will be low.
 
Is This Answer Correct ?    47 Yes 24 No

Answer
# 4
supply below 3.3 KV is considered as LT but in India it is
limited to 415V and from 3.3 to 11KV it is MV but some
people consider 11KV as HT, while from 11KV to 33KV and
above is HT
 
Is This Answer Correct ?    45 Yes 25 No

Answer
# 6
LT means low tension, less than 1000volts and voltage wiil
be loe and current will
high.
HT means high tension,higher than 1000 volts like
11kva,33kva,66kva. and voltage will be high,and current
will be
low
 
Is This Answer Correct ?    32 Yes 14 No

Answer
# 7
the downstream distribution is LT supply
before downstream supply is MV ( MEDIUM VOLTAGE)
Before MV Distribution is HV (HIGH VOLTAGE )
 
Is This Answer Correct ?    19 Yes 11 No

Answer
# 8
LT supply is in the range of 1100 volts.

HT supply is in the range of 6.6,11,22,33,132KV
 
Is This Answer Correct ?    7 Yes 0 No

Answer
# 9
LT & HT SENSE MEANINGFUL ONLY PLACE OF TERMINOLOGY.
CONSIDERING PUBLIC SENSE, DOMESTIC SUPPLY (230V),440V - THE
ONLY TWO STANDARD VOLTAGE SUPPLIES IS TERMED AS LT. THE NEXT
HIGHER VOLTAGE AVAILABLE IN INDIA IS 6.6KV (6600V ).THE 6.6
KV AND ABOVE ARE TERMED HT.

UNIVERSALLY VOLTAGE LESS THAN 1000V IS TERMED AS LT WHILE
ABOVE 1000V IS HT. AS ONLY 230V,44V ARE THE ONLY LOWER
VOLTAGES AVAILABLE IN INDIA FOR DISTRIBUTION, THE BOTH ARE
TERMED AS LT.
 
Is This Answer Correct ?    7 Yes 1 No

Answer
# 10
in indian power system
LT supply mean below 440V
HT supply mean above 440V
country vise margin might be upto 1000V
