XYH 12kva singlephase voltage optimisation

The declared electricity supply in the United Kingdom and Austrilia is now, as a result of European Harmonization in 1995, 230V with a tolerance of +10% to -6%. This means that supply voltage can theoretically be anywhere between 216.2V and 253V depending on local conditions. However, the average voltage supplied from the national grid is 242V, compared to the nominal European voltage of 230V. The average supply voltage in Northern Ireland is around 239V, and 235V in the Republic of Ireland.
