Abstract :
Published data for electrical tree inception field at a defect in XLPE vs. the Laplacian field at the tip of the defect are explained on the basis of a minimum distance which the space charged limited field must extend from the defect tip into the XLPE in order to damage enough dielectric in the field direction to facilitate PD inception and tree initiation
