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

  2. Non linear BehaviorCase: Current taken by IT equipement

  3. Non linear BehaviorTheoretical Considerations

  4. Non linear BehaviorTheoretical 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)
