IEC 63060 pdf free download.Electric energy supply networks – General aspects and methods for the maintenance of installations and equipment.
5.2 Principles and roles
The network operator is responsible for planning and developing maintenance and maintenance support. The network operator has to ensure the proper implementation of maintenance activities. The organizational responsibilities have to be defined, assigned, and documented for all maintenance activities.
During the concept, design and definition stages of an installation, maintenance principles shall be defined that consider:
— general aims of maintenance and maintenance support,
— applicable laws and government regulations,
— required reliability, availability, maintainability (including testability), safety and health, environment, and costs,
— general specifications for maintenance and maintenance support.
The network operator is responsible for:
— defining maintenance principles,
— assuring that implementation and planning of maintenance is achieved,
— reviewing and adapting maintenance concepts with respect to operating experiences.
For this purpose, the network operator has to provide adequate resources (e.g. budget, staff, and spare parts). The general procedure for performing maintenance is defined by maintenance principles that serve as a guideline for planning, implementation, benchmarking, analysis, and improvement of maintenance. The principles have to be documented.
The principles for planning maintenance activities are defined by the network operator. With regard to grid development and grid planning, the planning of maintenance is oriented on long, medium, and short term operational objectives, as well as regularly occurring condition changes of equipment and installations.
The specifications of maintenance and maintenance support have to be verified on a regular basis to consider changes in legal frameworks, operational requirements, and the development of maintenance procedures. Corresponding changes may be necessary due to the age of the object or based on the results of diagnostic tests, if available. If new equipment or installations are added or modifications are implemented, required adjustments in maintenance and maintenance support should be considered.
If training is required, training documents, tools, and equipment have to be identified and provided, before entering the operational and planning phase. The training also has to be performed during the phase of operation and maintenance.
Technical manuals and technical documentation should contain the information and procedures that are necessary for the correct, safe, effective and economic implementation of maintenance tasks.
7.2 Statistics
If appropriate, the network operator has to use a standardized, repeatable procedure for collecting and analysing data for the assessment of results. It should be based on corporate and sector-related factors, if applicable. The results should be used to support and to justify improvements. Possibly, a computer based maintenance information system for data management and analysis is needed.
NOTE The exchange of information between different system operators regarding the results of maintenance is not covered by this document.
Statistics of failure and, if appropriate, damage are to be kept in order to draw conclusions about the behaviour of equipment or components. Thus, the volume and timing of maintenance work can be oriented on statistical quantities. The maintenance plan is adjusted, if necessary.
The effectiveness of maintenance and maintenance support has to be monitored. For this purpose, selected properties have to be detected at certain objects, such as:
— availability, functionality, and maintainability,
— mean time between failures,
— mean time to repair.IEC 63060 pdf download.
