Direct current field test for medium voltage cables: why can no one agree?

Industry standards for shielded medium voltage power cables, 5 through 46 kV, have recently been revised, changing the direct current test voltages for field tests and test durations, and limiting tests to newly installed cables. The following industry groups' specifications and standards provide different guidelines for DC field tests for cross-linked polyethylene and ethylene propylene rubber insulated cables: Institute of Electrical and Electronic Engineers (IEEE); Insulated Cable Engineers Association (ICEA); and the Association of Edison Illuminating Companies (AEIC). These specifications and standards are discussed showing the differences in the recommendations and why the differences exist. The conclusion provides a guide for the DC field testing of shielded medium voltage power cables based on these industry standards.
