Summary
Over the past 15 years, online-Transformer monitoring system TMS has been a key focus area for power utilities, In this paper, A leading GCC utility in the Gulf region, based in Qatar, presents its extensive experience in optimizing the deployment of advanced power transformer monitoring technologies as essential tools for ensuring the health and reliable performance of its transformer fleet within the transmission network.. These systems are widely deployed across transmission substations and industrial facilities connected to the utility’s network.On this regard, a techno-economic analysis study has been made by the utility’s specialized team to assess various factors that significantly impact the performance and economic viability of implementation of such TMS transformer online monitoring systems to validate its rule in contribution to overall network reliability, considering the fact of their costs can influence the overall ROI (Return of Investment). Factors such as harsh conditions, equipment costs, operational expenses including routine and corrective maintenance with labor costs, in addition to budget allocation for procurement of TMS online monitoring system spares/consumables.

To maximize the benefits derived from the installation of these systems, the utility takes an initiative role for analyzing these aspects with respect to system operational challenges which discussed in detail in this paper. The study seeks to strike a balance between system performance and cost-effectiveness by proposing an improved operational approach. This approach involves modifications to the existing TMS frameworks deployed across the transmission network, along with target recommendations to mitigate operational challenges. The proposed framework includes sitelevel enhancements aimed at improving the robustness of monitoring units, reducing failure rates, and mitigating component aging. Furthermore, a novel algorithm for filtering Dissolved
Gas Analysis (DGA) alarms is introduced, enabling them to distinguish between genuine fault conditions and anomalies resulting from data inconsistencies or acquisition failures. This approach demonstrates a substantial reduction in false alarms, improved data reliability, and a significant decrease in unnecessary maintenance interventions. The results indicate that centralization of critical diagnostic data such as (DGA), with effective management of its associated combined systems provides a practical and scalable approach for enhancing TMS performance and operational efficiency. The insights and methodology presented in this study can serve as a valuable reference for transmission utilities within the GCC and in other regions with similar objectives, supporting improved network reliability and cost-effectiveness in power transmission systems networks.
