The future is condition monitoring
It’s been a big month here at Hansford Sensors. We kicked off November by celebrating our 10thanniversary, during which time we were playfully predicting what our company may look like in another decade. While our thoughts on this are strictly hypothetical at this stage, thanks to the release of a new report we now have a better idea of the state of the condition monitoring market. ...

Motice - Greater Value & More Added Value
With Motice, users are presented with a system that addresses maintenance failures ahead of time. Condition monitoring systems (CMS) make wear and tear predictable, thus making repairs plannable and downtime less frequent: Signals from the machine offer added value because predefined signals can be used to detect deviations that warn of increasing wear. Thus, malfunctions can be prevented. ...

Online condition monitoring of electrical power system imbalance
Symmetrical components are of great importance in many applications in electrical power systems, such as power protection and condition monitoring. This paper presents a computer-based algorithm for online symmetrical components estimation. The proposed algorithm uses the samples of the phase variables (currents or voltages) to estimate the magnitude and phase angle of each phase phasor at each ...

ANN based real time incipient fault detection and protection system for induction motor
Artificial neural network (ANN) has its unique advantage in the area of incipient faults detection. This article presents an ANN based real time fault detection and protection system for two types of incipient faults viz. inter-turn insulation failure and bearing wear in single-phase induction motor. The ANN fault detection (ANNFD) program is developed in C++ and implemented using a PC based DSP ...

Wallem and AO Schiffahrt uses FluidScan for Shipboard Condition Monitoring - Case study
With depressed freight rates and overcapacity of shipping on lucrative trade routes, most shipping companies across the world are now practicing "slow steaming" operations. Operating the main "two-stroke" engines at 40-60% of their nominal output results in dramatically lower fuel costs but at high risk of cylinder cold corrosion if lubrication is not carefully managed. Adding to the complexity ...

Detection of inter-coil short circuits in coils of salient pole synchronous generator field winding on the basis of analysis of magnetic field in the machine
Abstract This paper deals with detection of inter-coil short circuits in coils of the salient poles synchronous generator excitement winding on the basis of the analysis of the magnetic field in the machine. Applying FEM to the generator model, magnetic field wave forms in the machine, on the points of interests, under both, faultless and faulty conditions were calculated. When results were ...

Measuring water with the Fluidscan fluid condition monitor
Abstract Water in oil can manifest itself in many forms – from dissolved to emulsified, to free water with oil. How water will be present in a given oil depends on the nature of the oil formulation as well as sample preparation conditions. The FluidScan® mid-infrared spectrometer from Spectro Inc. is designed to monitor the presence of water in all the above scenarios. The device uses ...

Bearing fault severity estimation using time–based descriptors for rotating electric machines
This paper evaluates the bearing fault severity in rotating electric machines based on the time–based descriptors derived from machine vibration signal. Time–based descriptors are independent of bearing dimensions and machine dynamics. To establish the relationship between the time–based descriptor and bearing fault severity, a wide range of defective bearings are examined on an experimental ...

CMSWIND - Case Study
Objective: The CMSWIND project consisted of the development of an advanced monitoring system for rotating components in wind turbines by means of the application of novel non-destructive testing techniques that were not previously being used in the wind sector. This new Condition Monitoring system improved component reliability by up to 50%, using a blend of vibration analysis (VA), motor ...

Correlation of dielectric model parameters with experimental results based on PDC, RV and loss factor measurements for high voltage capacitors
To improve the reliability and quality of electric power systems, preventive diagnosis and regular maintenance of high voltage capacitors are required. Dielectric response measurements in both time domain and frequency domain are potential tools for assessing the condition of dielectric of high voltage capacitors. Modern measurements in time domain include polarisation and depolarisation current ...

Vibration-based approach to lifetime prediction of electric motors for reuse
This paper is concerned with lifetime prediction of components in washing machines. Vibration signals were measured on electric motors during an accelerated lifetime test ranging from 26.7 to 38.5 simulated years. Loose bearings have initiated air-gap eccentricity and rotor-to-stator rubbing, which resulted in a motor breakdown. Significant frequency bands were identified using a spectral ...

How an Australian environmental coastal restoration project was kept on track using Acoem Eagle condition monitoring
Acoem has been providing condition monitoring and maintenance solutions to a major civil contracting company in South Australia for close to a decade. When the company needed assistance with a longstanding issue it was experiencing with its pumping equipment on an environmental restoration project, commissioning an Eagle wireless system was the answer. Structural damage to critical machinery ...
