<p>System for measuring and monitoring the moisture of insulating oil of power transformers and similar preferably applied to power transformers and reactors and similar. This system extends the utilization time and increases this equipment safety, wherein said system comprises a sensor module (M) installed in contact with the oil and an interface module (I), both permitting online measuring and monitoring of the water content in the oil, providing key information for diagnosis of the equipment condition. Based on this information, the proposed system allows to program (P) limiting values for activation of alarms (A) for high (A1) or very high (A2) water saturation content percentage; high (B1); or very high (B2) water content; and development trend of high (C1) or very high (C2) water content.</p> |
