Wiki Xfmr is an app for basic calculations related to transformer. It has five options. 1) Ratio 2) Current 3) No Load Loss Conversion 4) LoadLoss Conversion 5) Efficiency Calculator
1)Ratio Calculate ratio of the transformer for nominal voltage and for all the taps by entering the primary and secondary voltage of a transformer.Enter the number of plus side taps, minus side taps and the taps percentage. For example - primary of 12470 with +2-2 Taps at 5% apart. will have 4 taps 2 above 2470 and 2 below 12470. Tap the ratio button to calculate the ratio with standard 0.5% tolerance.
2)Current Calculate the rated amperes, and short circuit capability of the transformer by entering primary voltage,secondary voltage,kva and percent impedance.
3) Load Loss Convert the loadloss from one temperature To to a new temperature by entering individual winding losses and stray losses . Select the material of the winding for accuracy.
4)Noload loss Convert noloadloss from one temperature to another using this screen.
5) Efficiency Efficiency of the transformer can be calculated by entering kva,losses, power factor and load factor. For 50% load choose 0.5. Please send us your comments, so we can refine the application. Use the application at your own discretion. We are not responsible for any consequences related to the usage of the formulas.

An Email and clear option exist for all the screens. Users can now email the calculated results. They can also clear the results. The app will compose an email message containing the input values and the result values and prepare a email draft. More features coming soon.

I came across many blogs to know about the Voltage Transformer but after a long time i found my answer from your blog. Really i fully impressed on your contents.Thanks a lot.
