RESUMO
An important competitive edge of electric power distribution companies is their electric assets utilization management. Among them stands outs the power transformers because of its strategic importance in the energy supply to high demand areas. To minimize operational and social impacts associated to the electric energy supply interruptions these equipments must to have their main characteristics constantly monitored to have effective control and optimizer functioning warranty. The main characteristics monitoring is a critical point which must be constantly improved, for the unquestionable importance of these electric assets in the electric energy supply continuity. This work shows a proposal to the real time power transformer failure, to remote monitoring by the utilities thru its respective electric system operation center, enabling assertively and fast management decision making in internal failure occurrences, reducing costs associated with electric energy supply interruption, decreasing the supply reestablishing times and consequently minimizing the impacts on the main distribution operational quality indicators.
