Transporting the "harvested" energy from offshore wind farms over great distances to the densely populated areas where electricity demands are high is a difficult undertaking. Subsea high voltage direct current (HVDC) transmission lines are the future for these underwater “electricity superhighways”. HVDC can transport more electricity, but almost more importantly, more efficiently than traditional AC

With the increasing emergence of green energy from wind and solar power, the center of gravity within the transformer industry has been slowly shifting from large power transformers to distribution transformers. Simultaneously regulatory bodies, such as the Department of Energy, have introduced new minimum level performance requirements so that design changes are enacted to increase

A large percentage of electrical apparatus failures are due to the deteriorated condition of the insulation. Many of these failures can be anticipated by conducting routine testing and timely maintenance. Changes in the normal capacitance of insulation indicate abnormal conditions such as the presence of a moisture layer, short circuits, or open circuits in the capacitance
