SAŽETAK / ABSTRACT:
This paper focuses on the development and implementation of a system for oil pressure monitoring oil pressure of 110 kV cable lines with oil-impregnated paper insulation. The monitoring system enables continuous supervision and analysis of the cable system’s condition to ensure the reliability of electrical power transmission. Integration with the SCADA system allows real-time monitoring for system operator purposes. The system has the capability for automatic alarm activation in case of deviations from predefined parameter values. It generates notifications via SMS and email to the relevant system operator and maintenance departments, ensuring timely decision-making that can prevent electrical breakdowns in cable insulation and consequently interruptions in cable line operation.
Measurement results can be monitored at any time in graphical and tabular form. All data is archived, enabling later trend analysis of pressure changes. The experience of applying this system in the transmission network of the Republic of Serbia has proven to be highly positive, as it has successfully prevented potential failures in 110 kV cable line. The implementation of such a system contributes to reducing maintenance costs and enhancing the security of power transmission networks.
