it s the ratio of net cross section occupied by the magnetic material to the gross cross section of the core
generally, its value s between 0.5 to 0.95
What is meaning of Transformer sensitivity?
transformer is a static device hence it needs form factor.
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
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)
yes there is
What is meaning of Transformer sensitivity?
transformer is a static device hence it needs form factor.
It isn't! A transformer operating at no load has a very low power factor.
what is stacking factor?
The power factor is only taken into consideration when the Kilowatts of a transformer is used.
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
Transformer utilization factor is the ration of power delivered to the load and ac rating of the transformer secondary.
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)
When its load has a leading power factor.
When it supplies a resistive load.
