Voltage Drop

Creates a schedule called VOLTAGE DROP SCHEDULE and sets it to the active view. If a schedule of that name already exists, it sets it to the active view but does not otherwise modify it.

The default schedule layout is shown below. It lists each piece of electrical equipment in the project and information about the voltage drop. The devices are listed in "tree order" based upon the connections between devices in the model.

The VOLTAGE DROP column uses the DMET_VoltageDrop_Feeder_IgnoreXFMR shared parameter. This parameter displays a warning in the value for any voltage drop that exceeds 3%. To display the fault without any warnings, replace the column with the DMET_VoltageDrop_Feeder_IgnoreXFMR_NoWarnings shared parameter.

There are three ways to calculate the voltage drop through transformers. Each calculation method is available as a separate shared parameter. Use the shared parameter in your schedule that corresponds to the calculation method you prefer.

Ignore Voltage Drop in Transformers: The voltage drop through the transformers is ignored. Use the DMET_VoltageDrop_Feeder_IgnoreXFMR shared parameter. This is the default parameter used in the schedule.
Include Voltage Drop in Transformers: The voltage drop through the transformers is included. Use the DMET_VoltageDrop_Feeder_IncludeXFMR shared parameter.
Reset Voltage Drop at Transformers: The voltage drop is reset to 0% at transformers. Use the DMET_VoltageDrop_Feeder_ResetAtXFMR shared parameter.

Once the schedule is created, you can modify it using standard Revit MEP tools.
