摘要：

Electrical stress enhancement of contaminants in XLPE insulation used for power cables was studied. Metallic contaminants are found to increase the electric stress such that the local electric stress is higher than the breakdown strength. It was found that when establishing the purity level for insulations it is essential to choose the correct level of sensitivity and to routinely establish the size calibration of the detectors.
