Prioritization of maintenance activities from an electricity company

Due to aging and wear of the electrical equipment existing in power system and also due to the fast technological change is necessary to take timely and appropriate decisions (maintenance, repair, relocation, refurbishment, replacement) for moral or/and physically damaged components and adding supplementary elements (features), including the introduction of new technologies. This paper presents the concept of asset management as a complex process of decision-making on the assets managed by an electricity company, the stages of implementing an asset management system to quantify the real technical state of the equipment, and finally the importance of the power substations from an electricity company, with the aim to prioritize the maintenance activities. In addition to the theoretical presentation of the asset management concept, it was performed a determination card of the importance index of a power substation from power system.
