The voltage drop calculations are defined in the Rule Editor under /Analysis/Voltage Drop. Separate equations are defined for Radial and Meshed scenarios.


Some of the values from your calculation tables will need to be setup for the corresponding conductor models in the Industry Model Configuration (resistance and reactance values). Please refer to the Voltage Drop whitepaper (available on Subscription Center) for more information about configuring Voltage Drop analysis.

Hi, If you can provide any practical example that would make it easier for me to understand.

The Voltage Drop whitepaper explains the configuration and includes examples in the "Design Scenarios" section toward the end of the document. If your particular Voltage Drop scenario is not covered well by the whitepaper, can you please explain more about exactly what you need to setup for voltage drop?

I also recommend checking out the various /Analysis/Voltage Drop equations in the Rule Editor. If those equations do not match your local standards, you should be able to modify them to match your current calculations. Refer to the whitepaper to see how those equations are used in the overall calculations in the product. But most calculations are exposed in those rules and can be modified as needed.
