Hello everyone,
I am trying to model a three phase electrical cable in COMSOl to calculate Power loss.
Is there any model anybody can share or is there any video talking about electrical cable calculating power loss?
Thank for your help.

Hi,
There is a solution to your problem. If you already have drawn your model and energized it with a current, you can find the power loss by doing the following:
1. Click on "results"
2. Click on "derived values"
3. Choose surface integration
4. Select the desired domains for analysis (you can select all three phases if you like)
5. Apply the following expression under "Expression": mf.Qrh and click on evaluate.
The results will appear right below your model in a table. I hope this helps.
Best regards

Dear Officer,
Thank you so much. Should I use es or ec interface? Do you have any related model can share with me?
Thank you very much,

Hi Bin,
I am so sorry for keeping you waiting, I am a bit occupied these days with my master thesis.
You can see that I have attached a file. This file should work perfectly. It is three single phased cables in the frequency domain of 50 Hz, 150 A. The pipe in the model is (just for fun) made of aluminum, so you can also review the power loss in the pipe due to eddy currents.
Please let me know if I can help you with anything else, and give me a notice if you have problems with the model.
Best regards,
Tord
