Claim 21:
22. A sealing monitoring device for electrical equipment (10) comprising at least one sensor set (100), at least one signaling means (15) and at least one drying system (300), the sealing monitoring device for electrical equipment (10) being characterized in that the sensor set (100) comprises at least one moisture sensor (20) and at least one liquid presence sensor (25) connected to at least one centralizing element (30),
the moisture sensor (20) is configured to measure moisture in a compartment of the electrical equipment (10) and send a measured moisture value to the centralizing element (30), wherein
the liquid presence sensor (25) is configured to detect the presence of at least one between water and oil in a region where the said liquid presence sensor (25) is arranged and send a liquid detection signal to the centralizing element (30),
wherein the centralizing element (30) is configured to receive at least data from the moisture sensor (20) and the liquid presence sensor (25), grouping the data from the moisture sensor (20) and the liquid presence sensor (25) and build up a historical dataset and perform at least one among a liquid type determination, identifying a probable failure point in the sealing system, and identifying a failure criticality in the sealing, based on the data received at least based on detections by the sensor set (100),
the sealing being undertaken through a sealing system, wherein the sealing system is comprised of at least one among the bag (410) and the drying system (300) comprised of at least one drying means (35) and piping (40),
wherein the sealing system of the electrical equipment (10) is configured with at least one tank for the electrical equipment (10) that is divided into a fluid region (430) and a secondary region (440),
wherein the fluid region (430) is configured to receive the fluid into its interior,
wherein the secondary region (440) is configured to remain fluid-free in the absence of at least one failure in the sealing system and receive fluid into its interior, because of at least one failure in the sealing system,
wherein the sensor set (100) is installed and positioned on the secondary region (440), on a surface of the bag (410) that is not in contact with the liquid in the fluid region (430) of the expansion tank (400), wherein the at least one among determining the type of liquid, identifying a probable failure point in the sealing system, and identifying a failure criticality in the sealing is performed at least based on detections by the sensor set (100).
