초록

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.
