This paper introduces the design of a transformer load management (TLM) application program based on an automated mapping/facilities management/geographic information system (AM/FM/GIS). The data required for this application is mainly extracted from the databases of the AM/FM/GIS system and customer information system (CIS) and combined with customer daily load patterns obtained by load surveys over a long-term period. This integration environment including graphic and nongraphic databases enhances the TLM program by taking full advantages of AM/FM/GIS capabilities. The program provides a general system information inspection function as well as a load analysis and inquiry function which allow engineers to examine in detail the distribution system facilities or to perceive the loading conditions of a specified distribution device. In addition, the program provides a load distribution map overview function for easily investigating a feeder-wide load distribution through a full-color graphic screen. This application program can be applied to keep the distribution transformers from being damaged due to overloading or to prevent inefficient operation by reason of very light-loading conditions.
