Answer / bindu
KVAR-Kilo Volt Ampere Reactive, it is mentioned for
KVA-Kilo Volt Ampere,it is mentioned for Generator rating.

Answer / ganapati
KVAR= Ractive power
KVA= Apperant power
|Is This Answer Correct ?||16 Yes||4 No|
Answer / nkwocha obinna
KVA = V*I
KW = V*I*cos theta
KVAR = V*I*sine theta
kw is the real power
kva is the apparent power
kvar is the reactive power
|Is This Answer Correct ?||9 Yes||1 No|
Answer / arun
kva is apparant pawer which is used for transformer or generator rating
while kvar is reactive power kilo volt ampere reactive it does not do any work in the circuit only moves forth and back .
m i wrong ?
if yes suggest correct answer

Answer / venkatesh
from power triangle we have kva^2=kw^2+kvar^2
|Is This Answer Correct ?||8 Yes||5 No|
Answer / anand
KVAR is the reactive power utilised by the generators,
transformers, motors for producing magnetic flux
KW (true power) is the actual power or true power that
performs actual work
KVA ( Apparent power)is the vector summation of KW+KVAR
|Is This Answer Correct ?||2 Yes||0 No|
Answer / shriram gaur
this is used for measureing the total power fed into the
ckt, so generally used in defining the rating of the
transformer, also independent of PF.
KVAR - sqrt((KVA*KVA)-(KW*KW))
This is the correct relationship between the all three

what are balanced and unbalanced loads
I have 11KV/415V power distribution transformer. I have found unbalance current in LT (415V) side. Also observed that unbalance voltage (3V) at LV side due to HV side unbalance voltage. What should I check for this? Also, the same LV side load can run in balance on captive power.
