摘要

作者报告了一种能够解决未老化XLPE(交联聚乙烯)损耗的高压频域测量系统。该系统既可以分析谐波，也可以分析基频。最高工作电压为20kv，频率范围为0.0001 Hz ~ 1000hz。在22/spl℃的温度下，使用4 kV峰值电压在频域测量了不同的XLPE电缆样品(新电缆、人工老化电缆和现场老化电缆)。

High voltage dielectric response analyser for cable diagnostics

The authors report on a high-voltage, frequency-domain measurement system capable of resolving losses in unaged XLPE (cross-linked polyethylene). The system allows analyses of harmonics as well as of the fundamental frequency. The highest operating voltage is 20 kV and the frequency range is 0.0001 Hz to 1000 Hz. Different XLPE cable samples (new, artificially aged, field aged) were measured in the frequency domain using 4 kV peak voltage at a temperature of 22/spl deg/C.<>
