Answer Posted / manikanta..{munna} geethanjali
load is something which dissipates energy..!! in case of
transformer , ideally a transformer is power source
device...and but this acts as load practically bcoz of
losses in it...!!!
coming 2 d rating any load is alwayz rated in kw..!! here
in a transformer the losses are due 2 copper and iron which
depend on current and voltage respectively...there fore v
rate the transformer in v*i !!!! and they is no use of
including powerfactor.

WE HAVE THE DC RECTIFIER 1500A, INPUT VOLTAGE IS 3 PHASE. HOW TO CALICULATE THE LOAD? 3 PHASE SIDE EITHER dC SIDE. PLEASE SUGGEST ME
1)we have 1000 cfm Blower,Dia-1Mtr,Velocity of air 94 m/s 2)We have Natural Air velocity 94m/s 3If i Put Wind Mill in natural air ,speed is 94m/s Then it will generate Assume 100kw 4)If i put same wind mill across the Blower,air speed is same 94m/s now the Question is Will it generate 100 kw?

I have 2500KVA transformer delta/star,13.8KV/380V provided with LV 4000A breaker. Already I have 2300KW motor feeder with a full load 90%. Is it possible to connect another 1600A from that breaker? If so how the calculation is done?
explain why core loss of a transformer is almost constant under different load conditions when connected across a constant voltage and constant frequency.
