Hi ! kim seong-geun​ ,

You can obtain TDD values from the Harmonic Measurement Modules.

For that, you need to:

- Set up the "Display Mode" as "Magnitude Outputs Displayed as Percentages".

- Set up the "THD Display Mode" as "Percentages"

- Link the "Max Demand" input to the source for the peak or maximum demand load current. The demand load current might be a fixed value (provided with an External Numeric Module or Arithmetic Module), or it could be a maximum value over a period of time, calculated with a Sliding Window Demand Module and a Maximum Module.

Under these conditions, the TDD would be the "Total HD" output in your Harmonic Measurement Module.
