Field tests for UHV substations

Utilities worldwide, may be forced to consider using long distance bulk transmission of electrical energy due to a range of reasons and many are either implementing or planning UHV grids. In recent years, high economic growth can be observed in developing countries, and demand for electricity is increasing, mainly in large cities. To cope with these circumstances, new power plants such as hydro, coal fired, with improved emission reduction, and large scale wind farms, both on-shore and off-shore, are planned or under construction, and the need for high power and long distance transmission lines is increasing. In developed countries, the worldwide trend and the shift to a low-carbon society is dominant and therefore there is a potential need for construction of UHV transmission lines due to…
