To train in the various energy analysis and network pollution checks, the ideal situation would be to carry out the operations directly on genuine electrical installations. However, access to an electrical distribution cabinet (for example) does not always allow you to measure all the parameters frequently encountered on the network. Simulation is a particularly effective and safe way of gaining a concrete understanding of the effects of the variations in the current, voltage, phase angle and harmonic distortion that every electrician has to know how to deal with and rectify
