Hybrid Technique Based Voltage Stabilizers for XLPE Cable Insulation
Cross-Linked Polyethylene (XLPE) power cable is commonly used as the medium for transmitting power supply in the power system network. However, frequent exposure of XLPE cable to the high voltage causes its insulation to degrade over time leading to electricity outages. Electrical treeing is a commonly observed phenomenon associated with dielectric breakdown in solid dielectrics.
