Ulitization factor is how much of the designed total is used. My house is fed off a 50KVA transformer. It's capable of supplying 50KVA continuously, but it's probably only gets used at its' full potential every once in awhile (when my neighbors and I wake up in the morning, and when we get home from work and eat dinner, perhaps). Say it only gets used at 30KVA on average. The utilization factor would be 30/50, or 60%.
with a very good transformer you may get 95% efficiency
this is mostly due to eddy current losses in the core or magnetization losses
so with 100va transformer you lose 5 va
if you need 10va to charge your cell fone battery
with the 100va transformer 10va goes to the phone and 5 to keep the transformer warm
you wish to make a call while the phone is charging you need 5 plus the 10 to charge the battery a 20va transformer you only lose 1 to heat the wall wart
if you are out most of the day and want to charge it in 1/2 hour you need the 100va seems like extraordinary expense on the chance you forget to put it on the charger before you go to bed
Transformer utilization factor is the ration of power delivered to the load and ac rating of the transformer secondary.
transformer action doesn't depend on power factor that is why we indicate its rating in KVA
The power in a 15 MVA (15000 KVA) transformer depends on the power factor. You did not specify the power factor, so I will assume a power factor of 0.92. Simply multiply MVA by PF and you get 13.8 MW.
When it supplies a resistive load.
The inductance of the transformer is much higher than the resistance of the transformer, resulting in very low real power losses (in watts), but some reactive power (vars).
Transformer utilization factor is the ration of power delivered to the load and ac rating of the transformer secondary.
Utilization factor is a metric for power plants that describes how close the plant is operating to full capacity. For hydropower, utilization factor can be affected by droughts and seasonal variations in rainfall.
transformer is a static device hence it needs form factor.

3 phase 3 pulse form factor -> Edc= .675 Eac .675= 3/(pi*sqrt(2)) 3 phase 6 pulse form factor -> Edc = 1.35Eac 1.35= 2*(3/(pi*sqrt(2)))
It isn't! A transformer operating at no load has a very low power factor.
To calculate the utilization factor of GTG do the following =(Power generation/ (design capapility MWH* period hours))*100 hope i answer your question
The power factor is only taken into consideration when the Kilowatts of a transformer is used.
the importance of scale of preference to firms is right choices of goods to produce an efficient utilization of resources
zero volatge regulation means the terminal volatge of transformer at full load on a given power factor become equal to the rated teriminal volatge of transformer , it happens only for leading power factor in transformer
transformer action doesn't depend on power factor that is why we indicate its rating in KVA
It tells us how much is the transformer utilised in a given process. For a rectifier,TUF =(D.c.power delivered to the load)/(power rating of transformer secondary)
