what is the maximum load on for 10 kva & 25 kva transformer
Answer Posted / aruloli
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
Primary load current is
10000=1.732*230*I
I=25.10 A
Secondary is,
52.48 A

how brushed dc motor operating ?
would you please give me any idea about the BARC interview question on electrical? i have an interview on 1st july.....plz hlp me.......its urgent......
True or false question. 1.The fuse provide phase and neutral 2.power loss in electrical circuit can take place in (resistance or inductance or capacitance). 3.two phase system each phase has separated by a phase difference of (90 or 180 or 270 or 45). 4.3 phase balanced star connected load neutral current shall be (line current or phase current or zero or unity)

i am an maintenance engineer. one distribution board have 5 feeder. recently its ELR trips frequently, but it take some times after trip( 10min,20min..)but 3 feeder no load. two feeder only loaded. i checked one feeder IR value all values are above 50Mohm.but B phase to Earth is only 9Mohm.any problem about low value
