Monitoring of generators is an essential part when operating a plant in remote areas. Nowadays demands on system reliability are very high and thus maintenance at regular intervals is necessary. Standard fault detection methods are usually based on several additional sensors. Such monitoring systems increase system costs and afford an additional source of fault. To avoid this disadvantage an alternative...
The paper presents an application of a novel method for diagnostics of electric and magnetic asymmetry of rotor cage in induction motor due to broken rotor bars. Increasing anomaly in magnetic field distribution results in a degradation of steady-state and dynamic performance of induction motor. It can be determined through the analysis of the average duty cycle of the modulated voltage. Broken rotor...
