Special Issue Information

Short Introduction: Condition monitoring methods have now been used to determine machine health for many decades. At present, the ongoing developments in sensing, data, computing, infrastructure and advanced analytics mean that we are seeing unparalleled growth in the technologies being successfully applied to condition monitoring. This Special Issue entitled “Machine Health and Condition Monitoring” will review the breadth and depth of such developments, from the system level down to detailed individual elements within the system. Table 1 provides typical functions that will be covered.

This Special Issue will bring together papers detailing advancements enabled by the increased availability of sensors and data, used in conjunction with advanced analysis methods. This may include any aspect of condition monitoring, from novel or improved sensing, working with increased amounts of sensor data such as high-frequency continuous vibration data or video/high-resolution image capture, managing data quality, pre-processing, and feature extraction. We are also interested in works utilizing or improving existing knowledge such as physics-based models or incorporating domain knowledge through the use of NLP/text mining to extract useful information from text records such as equipment logbooks, maintenance reports or manuals. Research on the development of data-driven models using advanced statistics, machine learning/artificial intelligence for the identification and prognosis of machine health status, including digital twins, is also of interest. Further, we are accepting papers presenting methods for aiding asset management, such as decision support, operational research and optimization.

Power transformers are considered to be the most important assets in power substations. Thus, their maintenance is important to ensure the reliability of the power transmission and distribution system. One of the most commonly used methods for managing the maintenance and establishing the health status of power transformers is dissolved gas analysis (DGA). The presence of acetylene in the DGA results may indicate arcing or high-temperature thermal faults in the transformer. In old transformers with an on-load tap-changer (OLTC), oil or gases can be filtered from the OLTC compartment to the transformer’s main tank. This paper presents a method for determining the transformer oil contamination from the OLTC gases in a group of power transformers for a distribution system operator (DSO) based on the application of the guides and the knowledge of experts. As a result, twenty-six out of the 175 transformers studied are defined as contaminated from the OLTC gases. In addition, this paper presents a methodology based on machine learning techniques that allows the system to determine the transformer oil contamination from the DGA results. The trained model achieves an accuracy of 99.76% in identifying oil contamination. Full article
