what is the maximum load on for 10 kva & 25 kva transformer..

Dear Friend
You forgot to furnish few more data i.e Voltage rating of
primary and secondary.

If i assume Voltage rating for 10 KVA Transformer as 230
V/110 V (Primary/secondary)and considering as single phase .

primary load current is calculated as

P=VI

10*1000(VA)=230*I
I=43.47 A

Secondary current is ,
90.90 A

Considering Transformer as 3 phase, then

P=1.732*v*I

10000=1.732*230*I

I=25.10 A

Secondary is,

52.48 A

what is the maximum load on for 10 kva & 25 kva transformer..

10 kva & 20 kva means transformer apparent power that is
combination of active and reactive power so we can load this
transformer below its rating coz load means only active
power .but in case of purely resistive losd we can load this
transformer upto its rating but practically purely resistive

what is the maximum load on for 10 kva & 25 kva transformer..

aroluli which voltage we'll use ? line to line to line to line to ground ?? 230 or 400 this formula to calculate 3 phase current ?? p= 1.73 v i cos@

what is the maximum load on for 10 kva & 25 kva transformer..

the max load you already said as 10 kva and 20 kva. In terms
of kw it will be 10 & 2o kw also, so long it does not exceed
10 & 20 kva ampere ratings.

what is the maximum load on for 10 kva & 25 kva transformer..

hi all please remember in india 1 kva =1.33a then
10 kva = 13 ams use it only 80%load =13*.80=10.4 amp load
25kva*1.33=25 ams ams aprox we use 80% load 33.25*.80=26.6 a maximum load it is safty of trnsfomer

 Is This Answer Correct ? 1 Yes 2 No

what is the maximum load on for 10 kva & 25 kva transformer..

For 3phase transformer
10 KVA=10*1.4 Amp=10.4 Amps maximum
25 KVA=25*1.4 Amp=35.0 Amp max.
