It tells us how much is the transformer utilised in a given process.

What is the need of form factor in transformer?
transformer is a static device hence it needs form factor.
How much is the transformer utilisation factor for half wave rectifier?
0.287. I hope this is an academic question and not something you're thinking of using in a circuit; three more diodes are cheaper than the kind of filter you'll need to clean up the output of a half-wave rectifier - AND you throw away half the voltage the transformer is putting out!
What is the condition for zero voltage regulation of a single phase transformer?
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
Can you use ordinary transformer in place of auto transformer?
yes we can place auto transformer in place of original transformer
Is there any relation with vector group of transformer with power factor?
yes there is

Why transformer power factor taken unity?
It isn't! A transformer operating at no load has a very low power factor.
Is it a utilisation or an utilisation?
a utilization
What has the author Katharine S Neiss written?
Katharine S. Neiss has written: 'A monetary model of factor utilisation'
If power factor is 8 then how many ampere there will be in each phase of a 250 kva transformer?
The power factor is only taken into consideration when the Kilowatts of a transformer is used.
Why you use low power factor wattmeter on primary and unity power factor on secondary side of transformer?
There is no such thing as a 'low power-factor' wattmeter. A wattmeter always reads true power, regardless of the load's power factor.
What is the condition for zero voltage regulation of a single phase transformer?
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
Why you are indicating capacity of transformer in KVA?
transformer action doesn't depend on power factor that is why we indicate its rating in KVA
Why low power factor wattmeter is used for open circuit test of transformer?
For open circuit test of transformer, the secondary is open circuit and the circuit impedance is largely inductive due to the core impedance having high L as compared to R. hence the power factor is reduced, thus , we use low power factor wattmeters.
What are common efficiencies for transformers?
Transformer utilization factor is the ration of power delivered to the load and ac rating of the transformer secondary.
Which type of transformer is use in gss?
Frgi transformer
