“…Moreover, previous works have shown that when there is a broken bar fault the neighboring bars are overcharged and are expected in most cases to break subsequently [7]. Despite this, some cases have been reported where the broken bars were not in adjacent positions but in random positions along the rotor circumference influencing negatively the diagnostic reliability of Motor Current Signature Analysis (MCSA) [7]- [10] for this fault.…”

Abstract -It has been shown in the past that the zerosequence current spectrum can be reliably used to detect broken bar faults in induction motors. Previous work was carried out with extensive FEM analysis. Although it allows detailed study of spatial and time-dependent electromagnetic characteristics of induction motors, FEM is a heavily timeconsuming tool and this limits full study. So, in this work, extensive experimental testing has been performed to validate the zero sequence current spectrum for detecting rotor asymmetries. Three identical induction motors have been used: one healthy, one with a broken rotor bar, and one with two broken rotor bars. The motors were tested under different voltage supply levels and with different mechanical loads. The zero-sequence current spectrum was calculated after measuring the three phase currents. It is for the first time experimentally shown that this approach offers greater diagnostic potential than traditional MCSA. CURVE is the Institutional Repository for Coventry University

“…[20], [21] also dealt with this issue by developing models where the case of nonadjacent breakages is taken into consideration. In [22] a thorough study of the induction motor with non-adjacent broken bars is carried out. Finally, in [16] a physical analysis of the air-gap magnetic anomaly for the case of any double bar breakage is performed.…”

“…Studies have shown that the breakage of a bar leads to overcharge of the adjacent bars, which are expected to break next [10]. However, industrial cases have shown that broken bars can exist at non-adjacent positions also [11]- [12]. Although in general, a broken rotor bar does not lead to an immediate fast catastrophic machine failure, this is not always the case.…”
