Sommario/riassunto

This standard is intended to aid the electric power industry in reporting and evaluating electric generating unit reliability, availability, and



productivity. It was developed to overcome present difficulties in the interpretation of electric generating unit performance data from various systems and to facilitate comparisons among different systems. The standard should also make possible the future exchange o meaningful data among systems in North America and throughout the world. Scope: This document standardizes terminology and indexes for reporting electric generating unit reliability, availability, and productivity performance measures. A generating unit includes all equipment up to the high-voltage terminal of the generator step-up transformer. Reliability in this standard encompasses measures of the ability of generating units to perform their intended function. Availability measures are concerned with the fraction of time a unit is capable of providing service, and account for outage frequency and duration. Productivity measures are concerned with the total power produced by a plant with respect to its potential power production. Therefore, productivity measures consider magnitude of outage as well as frequency and duration of outage. NOTE - This standard was developed for application at the unit level; the definitions are applicable below the unit level in most cases. There are some exceptions, however, such as the definition of in service, which applies only at the unit level. Because of these exceptions, care should be taken when using this standard below the unit level.

Sommario/riassunto

Low-voltage power circuit breakers that are intended for use in field circuits of apparatus such as generators, motors, synchronous condensers, or exciters, and that embody contacts for establishing field discharge circuits are covered. Service conditions, ratings, and functional components are discussed. Temperature limitations and classification of insulating materials, insulation (dielectric) withstand voltage requirements, and test requirements are addressed. An application guide is included.
