so far i knew, the Transformers are used to seprate dc component from ac component of supply fed into primary winding of coil. still if dc output value of ac input has to be calculated then it is v2*2/sqrt(pi)
where v2 is peak ac output voltage and is equal to v1*n2/n1
pi is a constant numerically equal to 3.14
thus the dc value is average value of output ac voltage

What happens if a 208VAC primary voltage is connected to a 240VAC stepdown transformer to 208VAC?
The transformer will act as a step down transformer in the ratio of 240 to 208. This will reduce the 208 input to 180.
How do you calculate the transformer turns ratio?
For an ideal transformer, the voltage ratio is the same as its turns ratio.
You have 480 volts coming into a stepdown transformer that is set for 440 volts incoming power would this cause your output voltage to be higher than 120 volts?
In short, probably. Transformers step power up or down by a multiplicative factor based on the number of turns in the two transformer coils. Therefore, if you put more voltage in you're going to get a proportional increase in the voltage out.
The incoming voltage from the current source to the transformer is called what?
The incoming voltage from the source to the transformer is called primary voltage.
How do you calculate input voltage of a transformer given both side high and low side impedances and also load with power factor?
The input voltage (primary) and output (secondary) of a transformer is determined by the manufacturer. Transformers are bought to accommodate the voltage that is needed on the primary side and to what voltage is needed on the secondary side.
What does a step up transformer do at a powerplant?
It is used to step up the voltage in order to transmit it a long distance where it goes into a stepdown transformer and then into your home .
What happens if a 208VAC primary voltage is connected to a 240VAC stepdown transformer to 208VAC?
The transformer will act as a step down transformer in the ratio of 240 to 208. This will reduce the 208 input to 180.
How do you calculate transformer voltage ratio test?
Secondary voltage / primary voltage
How do you establish no of turns in both high voltage and low voltage windings of a 3 phase transformer?
Through the use of the basic transformer voltage equation.
How do you calculate the transformer turns ratio?
For an ideal transformer, the voltage ratio is the same as its turns ratio.
What happens to voltage when current is increased?
current is decreased Depends of the circuit or device: in a stepdown transformer: power in= power out, V x I = V x I , Increase voltage in (power remaining constant) you current output will increase.
How do you calculate transformer nubmber of turnes?
You need to apply the general voltage equation for a transformer. For the primary winding, this is:Ep = 4.44 Np f (flux)max... where Ep is the voltage induced into the primary winding, Np is the number of turns, and f is the supply frequency.The secondary turns can then be determined from the desired voltage ratio.
How to calculate short circuit protection for transformer?
don't overload it, have a look on the transformer their should be an input voltage and an output voltage if take fails just try and see if u can overload it when you do try and figure out the voltage and get a new transformer;)!!!!!

How do you calculate MVA rating of power transformer?
The product of the secondary rated current and the secondary rated voltage will give you the rated V.A of the transformer.
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
Why are transformers necessary?
Transformers are necessary to stepup or stepdown voltage levels so that transmission of power is convenient. without stepup/stepdown voltage level according to our requirement losses will be very high and transmission and usage of power is not feasible.
