What is the PI value of power transformer?
PI stands for polarization index. We need to find IR value(IR1) for 1min and again find the IR value(IR2) for 10min. PI=IR2/IR1
What is a half transformer and a half transformer?
a hole transformer
Why induction transformer called rotating transformer?
Transformer has windings
Can you use ordinary transformer in place of auto transformer?
yes we can place auto transformer in place of original transformer
What is the function of fans in transformer?
The function of fans in a transformer is to regulate the transformer's temperature.
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
The transformer utilization factor of full wave bridge rectifier is?
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)))
What is center tap transformer?
Center tap transformer is the such kind of transformer that is made to a point half way along a winding of a transformer.
What is the difference between isolation transformer and ferromagnetic transformer?
An isolation transformer is usually a ferromagnetic transformer. The question needs to be framed more usefully.
Why auto transformer is lighter than conventional type?
because the copper is saved in the auto transformer that is the ratio of weights of copper in auto transformer to normal transformer is (1-(1/a)) where a is transformer ratio
Difference between potential transformer and current trasnformer?
The difference between current transformer and potential transformer is that the secondary of a current transformer can not be open circuited while under service whereas that of the potential transformer an be open circuited without any damage to the transformer.
A transformer can only?
A transformer does many things.
