“…In this study, oil analysis technology is exclusively used in the condition monitoring (CM) parameters. The electrical testing was excluded in this study due to the shortcoming in this technology to detect a fault in the initial stage [3,18]. Measurable variables of oil analysis are demonstrated in Table 1.…”

“…Onsite electrical testing technology is also used in the maintenance strategy to identify the type and location of the fault. However, this technology is usually recommended at the transformer shutdown time for scheduled maintenance or when a fault is suspected [3,18]. Assessment of the transformer's condition, based on CM parameters, is a crucial key in the CBM.…”

Fire and explosion accidents of oil-filled electrical transformers are leading to negative impacts, not only on the delivery of energy, but also on workplace health and safety as well as the surrounding environment. Such accidents are still being reported, regardless of applying the regular maintenance strategy in the power plants. The purpose of this paper is to integrate a sustainability perspective into the maintenance strategy. The problem addressed is: how can we approach the relevant cost-effective sustainable maintenance for oil-filled electrical transformers? For this purpose, an empirical study in a power plant in Kuwait was introduced. The first stage was to carry out a sustainability assessment using the ABCD procedure. In this procedure, gaps to approach sustainability were identified and actions prioritized to close these gaps were demonstrated. Applying this procedure yielded an early fault diagnosis (EFD) model for achieving cost-effective sustainable maintenance using a fault trend chart based on a novel numerical method. Implementing this model resulted in an extension of the lifetime of transformers with suspected failure propagation, leading to a deferral of the replacement investment costs. The principal conclusion of this paper is the importance of viewing the maintenance strategy of transformers from a strategic sustainability perspective, in order to approach relevant cost-effective sustainable maintenance.

“…Hence, the safety and reliability of substations are considerably and strictly required for the power industry (Zhao et al , 2017). Many scholars and engineers focus on intelligent inspection and the whole life cycle maintenance to avoid the substantial economic loss due to the failure of electrical equipment (Mendler et al , 2011). At present, inspection robots have been extensively used to monitor the electrical equipment and effectively prevent accidents in substations, which excessively promotes the development of unmanned substations due to the advantages of convenience, simplification, reliability and intelligence (Cheng and Xiang, 2019; Wang et al , 2012).…”

Purpose The purpose of this study is to provide an in-depth understanding about the indoor-orbital electrical inspection robot, which is useful for motivating the further investigation on the inspection of electrical equipment. Currently, electric energy has a strong correlation with the economic development of the country. Intelligent substations play an important role in the transmission and distribution of the electricity; the maintenance of the substation has attracted intensive attention due to the requirement of reliability and safety. The indoor-orbital electrical inspection robot has increasingly become the main tool to realize the unmanned. Hence, a systematic review is conducted systematically reviewing the current technical status of the indoor-orbital electrical inspection robot and discuss the existed problems. Design/methodology/approach In this paper, the most essential achievements in the field of indoor-orbital electrical inspection robots were reported to present the current status, and the mechanical structures and key inspective technologies were also discussed. Findings Four recommendations are provided from the analyzed review, which have made constructive comments on the overall structural design, functionality, intelligence and future development direction of the indoor-orbital electrical inspection robot, respectively. Originality/value To the best of the authors’ knowledge, this is the first systematic review study on indoor-orbital electrical inspection robots; it fills the theoretical gap and proffers design ideas and directions for the development of the indoor-orbital electrical inspection robot.
