摘要

现场测试和广泛的实验室调查表明，定期诊断测试，如tan δ、电容和IDE(综合放电能量)提供了有关绕组绝缘相对状况的有用信息。每个测试参数都提供了有关应监测的定子绝缘状况的特定信息，并应监测尽可能多的诊断参数，以获得有关绝缘状态、质量和老化趋势的可靠和完整的信息。tan δ和电容倾斜度之间存在很强的相关性。

Experience with dielectric diagnosis of high voltage motors in service

Field testing and extensive laboratory investigations indicate that periodic diagnostic tests such as tan delta, capacitance, and IDE (integrated discharge energy) give useful information on the relative condition of winding insulation. Each test parameter provides particular information regarding the condition of stator insulation should be monitored and as many diagnostic parameters as possible should be monitored to obtain reliable and complete information regarding the state, quality, and trend in ageing of the insulation. A strong correlation has been shown to exist between tan delta and capacitance tip-ups.<>
