Fault detection of broken rotor bars in induction motor using a global fault index

Abstract: Induction motors play a very important part in the safe and efficient running of any industrial plant. Early detection of abnormalities in the motor would help to avoid costly breakdowns. Accordingly, this work presents a technique for the diagnosis of broken rotor bars in induction motor. Stator voltage and current in an induction motor were measured and employed for computation of the input power of one stator phase. Waveforms of the instantaneous power and line current were subsequently analyzed using the B… Show more

“…These indices have capability to be used in non-invasive fault diagnosis techniques. In [18] a diagnosis method based on a global fault index applied to the instantaneous power signal and line current signal for detection of broken rotor bars was proposed. In [19] a proposed algorithm based on the principal components analysis (PCA) allows an automatic classification of stator fault.…”

“…demuestran la bondad de este método para la detección de barras rotas [117], mientras que Didier. Razik [118] y sus colaboradores lo hacen para roturas parciales (media barra) y bajo nivel de carga (25%). Además, el método es más efectivo a la hora de la cuantificación y para separar fallos mixtos, comparado con los basados en el análisis de las tensiones y corrientes del estátor [119].…”

“…La medida de la potencia resulta muy sencilla y además se puede efectuar en línea, existen diferentes métodos para medir la potencia, como por ejemplo obtenerla del sumatorio del producto de la tensión por la corriente, para el cual se miden las tres tensiones y las tres intensidades de cada fase [32], o el sumatorio de la tensión entre dos fases por la corriente de fase [63], [64]. Para ello sólo son necesarios transductores de tensión y de corriente.…”
