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.

 Is This Answer Correct ? 17 Yes 1 No

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.

 Is This Answer Correct ? 7 Yes 1 No

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

 Is This Answer Correct ? 7 Yes 1 No

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.

 Is This Answer Correct ? 4 Yes 1 No
Ombir Godara

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
Naresh

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.

  Question Asked @ Answers Other Electrical Engineering Interview Questions why receiving end voltage increases in a system when capacitive load is added 1 it says in neutral wire current flows under normal condition, but when we put tester it wont glow, why? HCL 6 what is meant by phase &line voltage, how its differ from each other ? 5 why do we generate sinusoidal ac?can we generate some other waveforms by alternators? Siemens 11 In three phase supply why we use R Y B Colour not other. 3 what is pmg and its use 1 Elaborate the term "rotating magnetic field" APTRANSCO 2 what is the difference between thermal magnetic release and microprocessor based release breakers. what are the advantages of latter over the first one... TCS 5 what is the differnce between vector and phasor? are both same or there is difference between two term.? 5 Based on CPI/CGPA they shortlist the candidates & than directly start Interview so there is no Written Exam or GD Only PI.Interview held @ MNNIT , ALLAHABAD On-Campus on 6th,Aug, 2007 & the Questions asked to me by Interview Board ( 4 People) are from HR/SummerTraining/BTP/Subject-core, POWER SYSTEM & MACHINE. time duration of I/V is about 15-20 Minutes. HR- Q.1 Name,hobbies & About family background ? Q2.What u know abt NTPC ?? Q3.Why u want to choose NTPC as ur Carrier's starting i.e power sector not any other Oragnisation or sector ?? Techincal Questions- Q1.What is the reason for transformer Noise ?? Q2.Which material is used for making Transformer oil & How u measure its dielectric strength & Name the test ? Q.3 Which Machine u will prefer 2 use if flammble gases are coming out at a place & why ?? Q4.What is relation b/w Transmission Lines & Communication Lines ? Q5.What is the maximum capacity Synchronus Machine & total powerGeneration in our country ? Q.6 In india Power generation is at 50Hz while in America its 60 hz ,why so ?? Advantage or disadvantage ?? Q.7 Maximum Generation Voltage in india ? Q8. What is the Voltage regulation & why its required n how much is permissible ? & causes of voltage variation ?? Q.9 Why electric shock is feel ?? n in a Electric Train why we didnt feel that ? Q.10 Have u seen/ experience of any power plant/ industry related to the power sector ? so these are the questions which not too diffcult i think was asked to me. NTPC 6 why we changed the polarity of DC generator ? DMRC 1 what principle the cabel TV channels are transmitted? will you be able to check the power at the connector behind your TV with a tester?If yes what is the supply level? 1 For more Electrical Engineering Interview Questions Click Here
