Now, what will be the direction of the current? As we know from our magnetic field of straight current-carrying wire calculator , a current produces a magnetic field, and Lenz's law tells us that, 'the emf induced by the changing magnetic flux, will have a direction such that the magnetic field it creates, opposes the change in flux'.
A single phase transformer consists of two windings: the primary left and secondary winding right. When an alternating current passes through the primary winding, a changing magnetic flux occurs in its interior.
If a magnetic core is added, it will direct the flux through the secondary winding, which will induce a current on it remember, a changing magnetic flux induces an emf.
The resulting relation between the voltage on each winding is described below:. So, by changing the number of turns in the winding on each side, we can control the change in voltage between them. How simple is that! While a transformer is a really efficient device, and we use an ideal transformer in our transformer sizing calculator, there exist multiple sources of power losses, for example:. A 3-phase transformer uses the same principles as the 1-phase transformer.
However, 3-phase transformers are primarily for industrial use. Our calculator works as a 3-phase transformer calculator as well! So, unless you're really sure about what you're doing, please don't go and try to build it on your own. Although fun, it can be dangerous. The rating unit for a transformer is the kVA , kilovolt-ampere. It displays how much load current and voltage the transformer can withstand. If the load connected is resistive such as heaters or incandescent lights , it will consume active power , or power used for generating real work, which is measured in kW.
When an inductive load is connected instead motors or speakers , reactive power is consumed. This power doesn't produce actual work and is measured in kVAR, kilovolt-ampere reactive.
The apparent power combines both, its unit is the kVA read more about this in our kva calculator , and we use that as the transformer rating's unit because it doesn't distinguish between loads so that you can use either.
Its formula is:. The formula is straightforward. Rectifier viva interview questions with answers. What do the different body colors of the resistors mean?

Calculate N1 V1 N2 V2. N1, Number of turns of Primary Windings. V1, Primary Voltage. N2, Number of turns of Secondary Windings.
V2, Secondary Voltage. Frequency In Hz. Number of Turns. If Ns is more than Np then Vp is more than Vs. As the number of secondary turns increases, so does the open circuit voltage of the secondary. It is necessary that the CT is insulated for higher voltages. The insulation thickness is increased and the size of theCT is increased. A core balance current transformer is a ring-type current transformer through the center of a three-core cable.
The type of transformer used for earth fault protection is usually a current transformer. Contents How do you calculate winding area? What is 42 in transformer winding rule? How many winding does a transformer have? What is CT ratio in transformer? How many turns in a transformer? How do you calculate the number of turns? What is EMF per turn?

What is used for winding of a transformer? How do you calculate 3 phase current of a transformer? What is NP and NS in transformer? How do you calculate 11kV? Hence a step-down transformer will have a primary transformer voltage that is greater than its secondary transformer voltage.
A step up transformer converts the low voltage and high current from the primary windings of the transformer to a high voltage and low current value in the secondary windings of the transformer. Hence a step-up transformer will have a primary transformer voltage that is lower than its secondary transformer voltage.
