ARE YOU A ELECTRICAL ENGINEER ?
ARE YOU CURIOUS ABOUT ELECTRIC & CURRENT

Do you wish that you had a handy calculator that allowed you to calculate voltages, line currents, ratios, efficiency, load loss or no load loss?

You are out in the field and you want that information?

You are in your factory floor and you want that information quickly ?

If you have said yes to any of the above, then this is the tool for you.

With this tool, you can get information for all the above. you can make informed decisions about voltages, efficiency, load loss, no load loss, ratios and current.

This may be the best tool on the market for electric and current calculations. Do not miss out on this deal, get this tool now !!.

Wiki Xfmr is an app for basic calculations related to transformer. It has 7 calculators.

1.) IEEE Standards
2.) Voltage Calculator
3) Ratio
4) Current
7) Efficiency Calculator

********* 7 GREAT TOOLS *************

1) IEEE Standards
List of all IEEE standards applicable to Transformers. Tapping a listing takes you the IEEE page, where the abstract can be read.

2.) Voltage Calculator:
Given primary voltage and ratio of the transformer. Calculate the secondary voltage. A handy tool to quickly calculate the secondary voltage.

3)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.

4)Current
Calculate the rated amperes, and short circuit capability of the transformer by entering primary voltage,secondary voltage,kva and percent impedance.

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.

Convert noloadloss from one temperature to another using this screen.

7) Efficiency
Efficiency of the transformer can be calculated by entering kva,losses, power factor and load factor. For 50% load choose 0.5.

Use the application at your own discretion. We are not responsible for any consequences related to the usage of the formulas.

#### Novedades de la versión 2.0

Minor UI changes.
Updated the efficiency calculator title page.
