基于状态的维护（也称为预测性维护）需要诊断工具来确定何时发生显著的绝缘老化，从而确定何时需要维护以避免运行中故障。多年来，许多离线诊断测试和在线监测系统已被提出和实施，特别是在关键的电动机和发电机上。在过去的十年中，大部分的研究集中在改善现有的离线诊断测试和在线监测，如磁通量，局部放电，温度，端部绕组振动等，但是，一些较新的测试，如极化/去极化电流，介电谱和在线泄漏电流监测已被引入。这些测试和监测系统进行审查。转子绕组绝缘和定子绕组绝缘的测试和监测系统分别解决。
Condition-based maintenance (also called predictive maintenance) requires diagnostic tools to determine when significant insulation aging has occurred, and thus when maintenance is necessary to avoid an in-service failure. Over the years many off-line diagnostic tests and on-line monitoring systems have been proposed and implemented, especially on critical motors and generators. In the past decade, most of the research has concentrated on improving existing off-line diagnostic tests and on-line monitoring such as magnetic flux, partial discharge, temperature, endwinding vibration, etc. However, some newer tests such as polarization/depolarization current, dielectric spectroscopy and on-line leakage current monitoring have been introduced. These tests and monitoring systems are reviewed. Tests and monitoring systems for rotor winding insulation and stator winding insulation are addressed separately.
