Efficiency Comparator

Rex Power Magnetics' Efficiency and Payback Comparator for low voltage distribution and medium voltage power transformers can be utilized to compare the performance of various tranformers with known no load and load losses. the comparitor will graph the efficiency curve of up to three transformers, and if the cost of electricity and expected loading are entered, it will calculate the operation cost and payback between the transformers.

Low Voltage Distribution Transformer Comparitor		Medium Voltage Power Transformer Comparitor

How to use the comparator?

Download the Zip file by clicking on the image of Low Voltage (below 600V) or Medium Voltage Transformer Comparator. Unzip the file and save the .exe file on your desktop or other folder.
This software calculates a comparison of performance and total cost payback of transformers of different efficiency depends of Load Loss, cost elecricity and initial transformer cost. Complete the information required in the boxes, choose you kVA rate and press button "Compare Efficiency" or "Compare Cost".
