  2. It can also determine the fault spot and reason. this technology has been used in some technological fields and proved efficient. it has promoted the revolution of maintance system and the historial protection is replaced by preventive maintenance. with this technology, we can improve the reliability of machine and decrease the maintance fee. recently, reserch has pick up a fervent pace in the area of fault diagnosis of electrical machines. the paper simply analyzes the fault reason of electrical machines, stressly describes and explores the methods of condition monitoring and fault diagnosis such as partial discharge, stator current, rotating speed, vibration etc. fault prognosis is now include diagnostic feature, reason, spot. prodigious improvement in signal processing hardware and software has made this possible. primarily, these techniques depend on locating specific harmonic components of the fault. these harmonic components are usually diffirent for diffirent types of faults. automated tools such as fuzzy logic based system is also simply presented in the paper
