Application of Multi-sensors Information Fusion in Electric Motor Insulation Fault Diagnosis

With development of examination,signal operation and intelligent technology,fault diagnosis has a big advancement.But,AC motor fault diagnosis is a field of research with much uncertainty.Nowadays diagnosis is always based on signature of single parameter like vibration,current,temperature,and because of the uncertainty of modeling environment and signal processing method,decisions we make are sometimes even wrong.The paper analyzes the uncertainty in traditional insulation fault diagnosis method,and the multi-sensors information fusion method is applied to make a fault diagnosis,build the fusion fault diagnosis system.
