Power electronic devices are becoming very popular as they are linked with renewable energy sources. Their primary use is to switch between DC and AC waveforms so that the energy generated at locations such as wind farms and solar plants can be used by the power grid. Although ch

Repetitive transient aging is not a well understood phenomena in the high voltage world. For this reason, an aging waveform has been designed to understand what the scale of the impact of these pulses is on the paper insulation of a transformer. The times to breakdown between AC

Identifying future trends in the power grid is vital in the extension of the life of its already aging components. Fast transients are the new factors that need to be taken into consideration as their high repetitive frequencies and fast rise times accelerate the aging of the pap

Environmental factors used to have a major contribution to a transformer's aging process. Heat and humidity were the main reasons for the degradation of the insulation layer and caused corrosion to the oil tank. With power electronics being introduced into the grid, repetitive tr
