This recommended practice presents fundamentals of reliability analysis applied to the planning and design of industrial and commercial electric power distribution systems. The recommended practice helps conducting reliability analyses on industrial and commercial power systems. The document addresses the following aspects: • Basic concepts of reliability analysis by probability methods • Fundamentals of power system reliability evaluation • Economic evaluation of reliability • Data related to the cost of power outage • Extensive mechanical and electrical equipment reliability data • The complete U.S. Army Corp of Engineers Power Reliability Enhancement Program (PREP) database • Examples of reliability analysis of various industrial distribution system operating configurations • Continuous power delivery • Voltage sag analysis • Emergency and standby power • Evaluating and improving the reliability of existing electrical system • Preventative maintenance • Reliability and maintainability verification • Standard data collection techniques

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
