2. Each derating factor can either be 'variable' (added to strength states table allowing you to specify a value for each strength state) or 'constant' (provide a number directly). In this example we have set them to be variable.
4. Specify tags for the derating factors to apply to your conductors. Tags 'conda' and 'condb' have been created.
Note: The default Conductors derating factors in the Strength states table have been changed to 1 so that they do not compound.
The process for adding to poles is similar, follow steps 1 to 5 above to create and add the derating factors to your desired poles through either the library or a CSV import.
The next steps are as follows:
1. After the derating factor has been applied to the pole, we can then click on the pole itself and view the 'Structure' tab in the properties pane to see its impact on pole strength:
Note that by clicking on 'derated=' you can see the exact derating factor being applied. In this case, ConductorB is the same conductor B as created above and as such we are applying a factor of 18%
2. You can again choose to add multiple derating factors to a pole.
To add custom derating factors to crossarms, the derating factor must be added via the components library:
1. Open up the components library and choose the correct crossarm for your construction
2. Within the 'tags' box, choose the desired derating factor (as created for conductors):
3. You can then create a construction with this crossarm and the derating factor will be applied.
In the same way as crossarms, insulators can have custom derating factors applied via the components library. To add this factor, open up the library and choose the desired insulator to be derated:
