“…Thus, the MCSA technique cannot diagnose such faults [19][20][21]. The instant power technique has been suggested as an alternative non-invasive approach to MCSA for diagnosing bearing faults in an induction motor [22]. The mathematical model of the instant power technique provides an extra harmonic frequency related to the faults, and provides more information related to the health of the machine.…”

Centrifugal pumps are the fundamental components of most industries. They are used in almost every industry to transfer liquid through pipes. The breakdown of a pump causes heavy production losses, and hence, the development of an economical and user-friendly condition monitoring system is vital in order to estimate the health of a pump in a timely manner, and to avoid an unscheduled breakdown. The intrusive condition monitoring techniques (such as vibration analysis and acoustic emission) developed for the fault diagnosis of pumps utilize expensive vibration sensors, and these sensors need to be installed on the pump body for data collection. Non-intrusive techniques (such as motor current analysis) have been proven to be economical, but have limited capabilities for diagnosing the incipient faults in pumps operating in a noisy industrial environment. The electric diagnostic technique (EDT) proposed in this paper does not require the purchase of extra sensors, and instead utilizes the existing sensors, which are usually installed on the machines, to measure and display the motor line current and voltage. The EDT has been developed in the Laboratory Virtual Instrument Engineering Workbench (LabVIEW) so as to measure the three-phase line current, and then transform it into two-phase d–q currents. These d–q currents are plotted as patterns, and the statistical features of these patterns are used to segregate the centrifugal pump fault types. Detailed experiments and evaluations have been performed in order to check the viability of the developed EDT technique.

“…The LabVIEW program routines developed for the motor current signature analysis and instantaneous power analysis are shown in Figure 2. The characteristic defect frequencies for the motor stator current spectrum and instantaneous power spectrum were calculated using the mathematical model as described in [8,9,10] and are shown in the Table I.…”

Gears are used in the machines to transfer rotational mechanical power. The excessive vibration is produced due to malfunction of the gear which eventually causes machine breakdowns. Conventional vibration analysis method could reliably diagnose the gear faults but high cost of the vibration transducers is the main limitation of this technique. The non-intrusive stator current analysis has been the best alternative to vibration analysis technique. But the capability of the stator current analysis has been reported only on the full load conditions of the motor. This paper presents an alternative nonintrusive condition monitoring technique which utilize the both stator current and voltage to analyze the gear faults in instantaneous power spectra. The experimental test rig has been designed to compare the amplitude sensitivity of the stator current spectra and instantaneous power spectra for gear operating under medium load condition.

“…The MCSA was used by [4,18,26] to investigate the rotor, gear and bearing localized defects. It was shown that two sideband components at ( f e − f v ), ( f e + f v ) appeared in a spectrum of the MCSA and change in amplitude at those sideband components gives the indication of the fault.…”

“…Invasive techniques (vibration analysis, thermal analysis, acoustic emission) are very basic and reliable but the sensitivity to the installation position and sensors costs are their main limitations. Non-invasive techniques are based on the stator current measurements and does not need access to the machine for data collection [3][4][5]. The non-invasive motor current signature analysis (MCSA) method has been widely used in early 20th century for the analysis of bearing faults.…”

Induction motors are mainly used for variable load applications and it is vital to have a condition monitoring system with capabilities to diagnose motor faults in variable load conditions. The environment noise varies has non-linear relation with motor load and it challenges the decision making capability of the condition monitoring system. This paper addresses the issue of reliable decision making on the existence of bearing faults in variable load conditions. Two type of threshold schemes have been proposed to reliably diagnose bearing faults in Park vector modulus spectrum. The performance of the developed threshold based condition monitoring system has been analyzed theoretically and experimentally.
