Answer / pritesh
because transformer depends on voltage and current v*i not
a depend of how much power is transfer so thats why its
rating in KVA.

Answer / nagaraj .n (bush king)
because trasformer is connected to supply resistive lode
inductive lode &capaitive load .the power factor for those
load is different (lag or leding )it worked apperent power.
the unit of apperent power is volt-aamper.that why
transformer rated in kva.
(its my knowledge)
| Is This Answer Correct ? | 4 Yes | 11 No |
Answer / kishore
loss coming due to passing of voltage and current
| Is This Answer Correct ? | 1 Yes | 8 No |
Answer / lalu prasad jadav
because Transformer has Two winding.It becomes very hot
while in running condition.So a considerable amount of heat
loss occured.So the loss in Kw may vary.So Kw rating is
avoided and Kva rating is given in Transformer nameplate.
| Is This Answer Correct ? | 1 Yes | 9 No |
Answer / rajesh
transformer dosent consume power.it just step up/down the
voltage.thats why transformer mentioned in kva
| Is This Answer Correct ? | 2 Yes | 11 No |
Answer / kishor a. thakkar
because its load is variable. and motor load is
continuously so we measure in KW. and Trans. measure in Kva.
| Is This Answer Correct ? | 0 Yes | 16 No |
Answer / naresh
The unit of voltage in Volts
The unit of current in Amperes
When the energy transfer from primary ciruit to secondary
circuit power is constant. there is no involvement of power
factor. Due to this transformer rating in KVA not in KW
| Is This Answer Correct ? | 89 Yes | 132 No |
Answer / amol
The instruments which converts energy from one form to
another, rated in KW like motor etc which keeps same form
of energy will be rated in KVA like Transformer,stabilizer
etc
| Is This Answer Correct ? | 9 Yes | 52 No |
WHAT IS THE REASON FOR LOW VOLTAGE IN HOUSES?*
Show Details FROM:Muhammed Ikram TO:qa@allinterview.com Message flagged Saturday, June 4, 2011 10:07 PMMessage bodyHello all, i want to ask a question to all of you that what is VMM (voltage monitoring module )? how it work,s? i heard somewhere that it compare 1 phase voltage to other phase voltage. but there is also some setting on it. how to set it,s setting. please tell me briefly. Thank,s and Regard,s. Muhammed Ikram.
