Question
Which one is correct mVA or MVA. Whether both the units are 
same for the  transformer
 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
Both are correct mVA = mili volt ampere while MVA= mega
volt ampere.Yes it depends upon the rating of transformer.

Answer
# 2
MVA is the correct representation
both units r not d same
MVA refers to Mega volt ampere whereas mVA refers to milli
volt ampere
 
Is This Answer Correct ?    8 Yes 2 No

Answer
# 3
mva = mili volt amp. as in mobile charger.
MVA = mega volt amp. as in sub station.

Answer
# 4
MVA is the correct representation. No one will mention the
transformer rating in mVA. If the rating is small then they
will represent in kVA even small they will represent in VA.
Not in mVA.

For Example 50VA can represent in 50VA only not in mVA

Answer
# 5
both r the reating of transformer. mVA (milli volt ampere)
is the smaller unit while MVA (mega volt ampere) is the
bigger unit.

Answer
# 6
MVA is the correct unit to represent a transformer rating
it is rated either in KVA or MVA but not in milli volt
amperes.
 
Is This Answer Correct ?    3 Yes 3 No

Answer
# 7
Both mVA and MVA are correct unit but depends upon the
rating of transformer
1. mVA mean milli volt ampere, used for small rating
transformer
2. MVA means megga volt ampere used for large rating
transformer
 
Is This Answer Correct ?    1 Yes 1 No

Answer
# 8
MV.A (not 'MVA') is the symbol for megavolt ampere.and in some low volatge cases we consider VA that is (Voltage Ampere). where VA is the true vector sum of circuit power or reactive power.
So, i thik it is true. NOT 'mVA' in case of transformer.
