In the next article, we will continue discussing the last special case for Power and Distribution Transformers sizing calculations which will be Transformers with Large Motor Loads.

Introduction This software calculates the K-Factor of a load from the harmonic content according to US and European practice. B- Method drop down menu: Again you can select, from this drop menu, between calculating K-Factor according to the US standards or Factor K according to the European standards.

Forth: Making New Calculation File A- Input data: When selecting calculating K-Factor according to the US standards, the Magnitude of each harmonic order, shall be entered and this can be done by two different methods: Method 1 : Holding down shift, click and drag in a harmonic order to set the magnitude.

First part: Transformer Rating Calculator Enter values in yellow cells only. Download portable version — No installer, for Windows 10 64 bits. Download Transformer calculator 64 bits. Seems to work but will not let me enter any amperage for the primary. Hola no puedo instalar el programa por que tengo windows 10 64 bits, como puedo instalarlo. This software is very useful to me. Very timely because I am going to rewind transformer. The software is working in my bit windows. Thank you very much!!!

Those are facing 64 bit unsupported issue please follow the link and you will be able run and install this program easily.

B is also known as magnetic field induction. It is defined as the amount of electric current charge flow in amperes flowing through a unit value of the cross-sectional area. Current density is vector quantity, because it is specified with magnitude and a direction. It is denoted by J. If 60 amperes of current is flowing through a conductor with a given area of 10 m 2 , what is the current density?

From the above table we will select SWG of wire as the diameter is 1. From the above table we will select SWG of wire as the diameter is 7. A transformer has 40 windings in its primary core and 30 in its secondary coil. If the primary voltage is V, find the secondary voltage. If flux density is 1. Calculate the number of turns on primary and secondary. A single phase transformer has primary and secondary turns. If the primary winding is connected to a frequency 50Hz supply at V.
