SANCHEZ M, Olga Liliana; VELASCO MEDINA, Jaime  and  LOZANO, Carlos Arturo. Designing an application for managing distribution transformer load. Ing. Investig. [online]. 2006, vol.26, n.3, pp.85-92. ISSN 0120-5609.

This paper presents a software application for distribution transformer load management and calculating the electricity distribution network service quality index (i.e. EDS and EFS indexes). Transformer operation state, calculating core and coil losses and selecting distribution transformers based on technical-economic criteria using daily-load curves are the load management strategies presented here. The application consists of a programme allowing to data acquisition input, an Excel-based spread-sheet having the equations for calculating load management data and a user-interface presenting the load management application’s results. The application was validated by technical-economic evaluation of three distribution transformers when supplying demand.

Keywords : EDS (equivalent duration of service interruption) and EFS (equivalent frequency of service interruption) indexes; load management; load monitoring.
