A computerized numerical database on electrical insulating materials for power transmission and distribution applications

A computerized numerical database on electrical, thermal, mechanical, degradation and other properties of electrical insulating materials for overhead and underground electric power transmission and distribution has been developed. The database is continuously updated and upgraded following new developments in insulating materials for transmission and distribution systems. As a central source of technical and applications data on electrical insulating materials directly accessible online, this database is a valuable tool in developing, designing, and manufacturing insulating systems for electric utility equipment. The database is interactive, menu-driven, and user-friendly. It permits the direct mode of search/retrieval of data for specified materials, properties, and independent variables, and the inverted mode of search/retrieval of qualified materials that meet a set of specified property requirements (which is the computer-aided materials selection). It also enables units conversion, variable transformation, and interactive graphical display and manipulation of the retrieved data. The methodology for data compilation, evaluation, analysis, and correlation and the database development, content, and operation are presented and discussed
