Abstract

In this paper, the study of influence of DC voltage and AC voltage on residual voltage of XLPE Cable was presented. In the former case, when the DC voltage of -10.0[kV] was applied to XLPE Cable for 0, 600, 1200, 1800[sec], time constants were 2139, 1416, 939, 488[sec] and resistivities were 930, 615.65, 408.26, 212.17[${\Omega}{\cdot}m$] respectively. In the latter case, when the AC voltage of 4 and 6[kV] was applied to the same Cable for 600[sec] after applying DC voltage of -5.0[kV] for 600[sec], time constants were 215, 275[sec] and resistivities were 93.48, 119.57[${\Omega}{\cdot}m$] respectively. In this experiments, measurement voltage, charging time and measurement time were -8.0[kV], 30[sec], 600[sec] respectively.
