van der Blij, N.H. (author)Historically speaking, alternating current (ac) has been the standard for commercial electrical energy distribution. This is mainly because, in ac systems, electrical energy was easily transformed to diffierent voltages levels, increasing the efficiency of transmitting power over long distances. However, technological advances in, for example,...doctoral thesis 2020

Wu, J. (author)Occasionally sporadic defects in high voltage cable insulation may escape from detection by commissioning or maintenance tests. Usually these tiny defects will not initiate significant partial discharges or cause breakdown in the cable insulation system under normal AC operating condition and normal transient situations. However, nowadays more...doctoral thesis 2020

Shekhar, A. (author)Energy transition will inevitably lead to greater electrification. For example, it is anticipated that electrical energy demand will rise by at least 2-3 times by 2050 with increasing share of electric vehicles and heat pumps. This will translate to significant increase in power demand on the existing medium voltage distribution grid, resulting...doctoral thesis 2020
