Installation board mains power system analysis / loading of neutral conductor / unbalanced load

Consumption of non-sinusoidal current by electronic equipment, starting of large electric motors and asymmetric distribution of load or switching operations can lead to damaging feedback effects on the mains electricity grid and therefore diminish the quality of the power system itself. Similar symptoms can be caused by quality shortcomings of your own making, such as poor choice of conductor cross-sections, non-compliance with selectivity requirements and incorrect wiring of PEN conductors.
In order to recognise the effects and make appropriate assessments of them, it is essential to carry out thorough analyses of the power supply system by measurement.
