In‐situ observation of electrical tree evolution in epoxy dielectrics with internal cracks
High Voltage, 2021 Gas‐filled internal crack might appear in thermoset materials like epoxy resin during the equipment manufacturing, which would become a vulnerable local region to initiate the electrical tree, thus prone to cause insulation failure. The withstand voltage
