List of transmission and distribution components for use in outage reporting and reliability calculations

This paper identifies composite systems for which reliability calculations are performed and major components of transmission and distribution equipment for which outage data are recorded. Descriptions such as design and operating characteristics, type, application, etc. which can be used to classify or group components in analyzing outage data are also suggested. The important requirements of an outage reporting procedure are discussed in this report. The information in this paper can be used as a guide by the utility industry in setting up a standard transmission and distribution equipment data bank.
