Endurance of Epoxy Resin Cast Insulation With Interfacial Micro‐Crack Defect Under 50 Hz Sine and Kilohertz Square Voltages

High Voltage, EarlyView.
ABSTRACT Crack‐type defects are commonly found in epoxy composite cast insulation due to residual, thermal and external stresses. When combined with inverter‐type voltage stress, as in epoxy cast high‐frequency transformers (HFTs), the likelihood of insulation failure increases significantly. In this study, a method setting microcracks perpendicular to
