Answer / waqar ahmed
Total t/f loss depend on vA copper loses depend on current &irnon loses depend on voltage not on phase angel between ¤t.it is independent of load power factor thats why t/f is in kva not in kw.hope u wil be satisfied

Answer / guest
The transformer is designed to supply rated total power to the
load. So its rated in KVA and not in KW

Answer / ali
the transformer total power is sq root of (apparent power)2 + reactive power)2 ... so the apparent power is always in kva and it is also depends upon the current and voltage ratings

We have two Al.busbars each of size 125mm*10 mm connected in parallel.To increase the current rating ,can we connect third busbar of size 100mm*10mm in parallel to existing two busbars?In my opinion ,if we connect busbars of different sizes in parallel,then the busbar of lowest size will take much current.So this type of paralleling should be avoided .Am I correct?
