Special Issue Information

Dear Colleagues,

Electrical machines play an important role in the industry, performing crucial tasks in production, propulsion, power generation, and numerous other industrial processes. Hence, condition monitoring and the prognosis and diagnosis of the faults threatening the smooth operation of the machines are of utmost importance, as they can lead to minimizing downtime, avoiding financial loss and the threat to human life. as well as preserving the environment.

There are many traditional diagnostic techniques in use and under investigation today, yet with the world and technology moving rapidly forward, new horizons are also opening in the diagnostic field. The possibility of using the Internet of Things, powerful Artificial Intelligence tools, virtual sensors, cloud computing, and all the different technological solutions classified as Industry 4.0 options, more advanced, complex, but at the same time more precise diagnostic techniques can be used. There is a great opportunity for novel diagnosis approaches for electrical machines to be introduced, and at the same time, old and previously not very promising techniques can find new life due to advanced IT solutions, providing more computational resources and faster calculation and simulation times.

As the use of electrical machines in the world is rising rapidly in all the sectors of life, novel approaches to electrical machine fault diagnosis can show the way towards a more efficient use and prolonged lifetime for machines and lead to the introduction of different intelligent technologies in engineering.

Voltage-induced heating defect is a type of defect that may occur in transformation substation equipment. Although this type of defect is less common compared to current-induced heating defects, it is crucial to identify it due to its association with severe insulation degradation problems that require prompt intervention. However, the temperature variations caused by these defects may be relatively subtle, making it challenging to distinguish them in thermal images. In this work, considering the characteristics of voltage-induced heating defects and the scarcity of defect data, we propose a two-stage method for defect detection. In the first stage, we employ oriented R-CNN to detect oriented parts of the equipment, accurately localizing the centerline of each part. In the second stage, we extract the temperature distribution along the centerline of specific parts and discretize them as features. Subsequently, we train one-class support vector machines based on the features extracted from normal images for defect diagnosis. Experimental results demonstrate that the proposed method is capable of accurately detecting defects while maintaining a low false positive rate. Full article

Electrical machines are prone to various faults and require constant monitoring to ensure safe and dependable functioning. A potential fault in electrical machinery results in unscheduled downtime, necessitating the prompt assessment of any abnormal circumstances in rotating electrical machines. This paper provides an in-depth analysis as well as the most recent trends in the application of condition monitoring and fault detection techniques in the disciplines of electrical machinery. It first investigates the evolution of traditional monitoring techniques, followed by signal-based techniques such as spectrum, vibration, and temperature analysis, and the most recent trends in its signal processing techniques for assessing faults. Then, it investigates and details the implementation and evolution of modern approaches that employ intelligence-based techniques such as neural networks and support vector machines. All these applicable and state-of-art techniques in condition monitoring and fault diagnosis aid in predictive maintenance and identification and have the highly reliable operation of a motor drive system. Furthermore, this paper focuses on the possible transformational impact of electrical machine condition monitoring by thoroughly analyzing each of the monitoring techniques, their corresponding pros and cons, their approaches, and their applicability. It offers strong and useful insights into proactive maintenance measures, improved operating efficiency, and specific recommendations for future applications in the field of diagnostics. Full article
