摘要

许多实验旨在寻找局部放电光谱(1)、(2)与绝缘条件之间的关系，但尚未形成明确的共识。所描述的工作是一项更大努力的一部分，旨在更多地了解机器绝缘寿命与从电晕光谱和其他测量得出的诊断指标之间的关系。特别是，测试过程中使用的电压变化可以成为扩展脉冲高度分析(PHA)和脉冲相角分析(PØA)有用性的有用参数。

Voltage dependence of corona signature from defect stator bar insulation during aging

Many experiments have been aimed at finding a relationship between partial discharge spectra (1),(2) and insulation condition, but a clear consensus has not yet been formed. The work described is part of a larger effort designed to learn more about the relationships between the life of machine insulation and diagnostic indices derived from corona spectroscopy and other measurements. In particular, it is shown that variations in the voltage used during testing can be a useful parameter in extending the usefulness of both pulse height analysis (PHA) and pulse phase angle analysis (PØA).
