Full title and description

IEEE Std 3006.3-2017 — IEEE Recommended Practice for Determining the Impact of Preventative Maintenance on the Reliability of Industrial and Commercial Power Systems. This recommended practice describes methods and procedures to evaluate how preventative (preventive) maintenance activities affect the reliability, availability, and failure behavior of industrial and commercial electric power systems, and provides guidance for engineers and maintenance planners on modeling, data collection, and analysis of maintenance impact.

Abstract

The standard presents recommended approaches for quantifying the effect of preventative maintenance on power-system reliability. Topics include reliability metrics (availability, mean time between failures, failure rates), selection and modeling of failure modes, methods to incorporate maintenance schedules and effectiveness into reliability calculations, data requirements, and worked examples tailored to industrial and commercial power-system equipment and configurations. It is intended to help engineers assess whether maintenance strategies achieve desired reliability objectives and to support cost–benefit trade-offs for maintenance planning.

Scope

This recommended practice covers methods to determine and quantify the impact that preventative maintenance activities have on the reliability performance of electrical power systems used in industrial and commercial facilities. It includes defining reliability objectives, identifying relevant equipment and failure modes, establishing data needs (failure/repair/maintenance effectiveness), applying probability and availability analysis techniques that incorporate maintenance actions, and illustrating the methods with examples relevant to industrial and commercial power distribution equipment and configurations. It does not replace equipment-specific manufacturer guidance or mandatory regulatory requirements but complements them by providing a reliability-analysis perspective for maintenance planning.

Key topics and requirements

• Definitions and reliability metrics: availability, MTBF, MTTR, failure rate and related measures.
• Techniques to model how preventative maintenance changes failure probabilities and repair/restore behavior.
• Data collection and quality requirements for meaningful reliability assessment (failure history, maintenance records, test results).
• Methods for performing probability-based reliability and availability analyses that include scheduled maintenance and maintenance effectiveness.
• Guidance on conducting cost–benefit and sensitivity analyses to evaluate maintenance program alternatives.
• Worked examples and recommended calculations tailored to industrial and commercial power-system equipment.

Typical use and users

Primary users are power-system and reliability engineers, maintenance planners, facility electrical engineers, consultants, and asset managers responsible for industrial and commercial electrical distribution systems. The document is useful for teams evaluating maintenance program effectiveness, preparing reliability-based maintenance plans, performing cost–benefit trade-offs for maintenance intervals, and for those conducting reliability studies that must incorporate maintenance actions and schedules.
