1. Analysis of the influence of non linear loads on power dissipation of LV cables
J. Desmet, D. Putman

2. Non linear Behavior Case: Current taken by IT equipement

3. Non linear Behavior Theoretical Considerations

4. Non linear Behavior Theoretical Considerations

5. Cable Temperature: Evaluation
Temperature for balanced symmetric linear and nonlinear load (XVB cable 4*2.5mm²)

6. Cable Temperature: Simulation
Simulated temperature distribution for balanced symmetric linear and nonlinear load 20A/phase (XVB cable 4*2.5mm²)

7. Conclusions
Few triple n harmonics in distribution, so no special measures
However in building distribution with a high number of IT loads, excessive neutral conductor currents occur so cable overheating is possible.
Extra power losses are found (increase up to the double of linear load)
