Web25 aug. 2014 · However, that's by no means the end of the story on regulation. The mains voltage can be expected to vary by up to ±10% from the nominal supply voltage (see Note below). So, if the mains is nominally 230V, expect it to vary between 207V and 257V. 120V mains can vary between 108V and 132V. Web1 jul. 2024 · In a mains power supply system that is a three-phase system, the neutral point is supposed to have zero potential when the loads on each phase are balanced. This is seldom the case. Large currents on one phase will cause the neutral to ‘float’ up, causing voltage fluctuations on the other phases. WebThe first detail is an understanding of how mains voltages vary across the world. More than one overseas manufacturer has been fooled into thinking that the mains voltage in the UK (& Eire) has been reduced to 230V, and some are careless enough to sell products made for 220V for use EU-wide. project plan 3 trial download
