“…At the moment, the Electrochemical Impedance Spectroscopy method is widely used to monitor the corrosion processes in various environments [ 68 , 69 , 70 , 71 , 72 ]. This method is used to study the structure of corrosion deposits and the mechanism of their formation [ 73 ], the resistance of coatings on the surface of materials [ 74 ] and the effectiveness of corrosion inhibitors [ 75 ].…”

Controlling oxygen content in the primary circuit of nuclear reactors is one of the key tasks needed to ensure the safe operation of nuclear power plants where lead-bismuth eutectic alloy (LBE) is used as a coolant. If the oxygen concentration is low, active corrosion of structural materials takes place; upon increase in oxygen content, slag accumulates due to the formation of lead oxide. The generally accepted method of measuring the oxygen content in LBE is currently potentiometry. The sensors for measuring oxygen activity (electrochemical oxygen sensors) are galvanic cells with two electrodes (lead-bismuth coolant serves as working electrode) separated by a solid electrolyte. Control of corrosion and slag accumulation processes in circuits exploring LBE as a coolant is also based on data obtained by electrochemical oxygen sensors. The disadvantages of this approach are the low efficiency and low sensitivity of control. The alternative, Impedance Spectroscopy (EIS) Sensors, are proposed for Real-Time Corrosion Monitoring in LBE system. Currently their applicability in static LBE at temperatures up to 600 °C is shown.

“…The presence of rust and corrosion not only undermines the structural integrity of transformers but can also negatively impact their performance and lifespan. Early detection and accurate assessment of these defects are crucial to prevent catastrophic failures and maintain the efficiency of the power grid [37,38].…”

Transformers are a very important asset in the electrical transmission grid, and they can suffer from destructive events—e.g., rare transformer fires. Unfortunately, destructive events often lead to a lack of data available for investigators during post-event forensics and failure analysis. This fact has motivated our design and implementation of a robotic multi-sensor platform and cloud backend solution for the lifecycle monitoring, inspection, diagnostics, and condition assessment of transformers. The robotic platform collects data from specific viewpoints around the transformer during operation and at specific relevant lifecycle milestones of the transformer (e.g., at the factory acceptance test) in an automated, repetitive, precise, and reliable manner. The acquired data are stored in the cloud backend, which also provides computing resources and data access to relevant in- and off-premises services (e.g., respectively, SCADA systems, and weather reports). In this paper, we present the results of our first measurement campaign to showcase the value of our solution for transformer lifecycle monitoring, for anomaly detection, and as a crucial tool for post-event forensics in the case of destructive events.

“…Depending on the extent of the corrosion, a structure linked to or in contact with a corroded region might undergo deformation. Research on the corrosion process and its monitoring has been conducted across numerous disciplines [1][2][3][4][5]. These methods included directly tracking the corrosive environment [6], analyzing electrochemical signals in metals that were generated or altered owing to corrosion [7][8][9][10][11][12][13][14][15], assessing specimen weight fluctuations induced by corrosion [16], evaluating structural deformation resulting from corrosion [17][18][19][20], and examining alterations in the wave propagation characteristics of metal components owing to corrosion [21,22].…”

The timely and cost-effective identification of the onset of corrosion and its progress would be critical for effectively maintaining structural integrity. Consequently, a series of fundamental experiments were conducted to capture the corrosion process on a steel plate using a new type of plastic optical fiber (POF) sensor. Electrolytic corrosion experiments were performed on a 5 mm thick steel plate immersed in an aqueous solution. The POF sensor installed on the upper side of the plate and directed downward detected the upward progression of the corrosion zone that formed on the underside of the plate. The results showed that the POF sensors could detect the onset of the upward-progressing corrosion front as it passed the 1 and 2 mm marks related to the thickness of the corroded zone. The POF sensors were designed to optically identify corrosion; therefore, the data obtained by these sensors could be processed using a newly developed graphic application software for smartphones and also identified by the naked eye. This method offered an easy and cost-effective solution for verifying the corrosion state of structural components.
