Hi Mohamed,
As per the titile of the question, I am assuming that you would like to get the equations used in the Power cable parameters App.
I am not sure whether all the equations used in the application will be publicly available for confidentiality concerns. However, you can go through the documentation of 'power_analyze' function which is used in the Power cable parameters App. In the docuemention few of the equations are disucssed.
You can refer to the following link to go to the 'power_analyze' documentation:
You can also explore the list of the function used in the Power cable parameters Application using the following link:
Hoping this answer your query!
