IEC 63060 pdf – Electric energy supply networks – General aspects and methods for the maintenance of installations and equipment
This document provides guidance to develop maintenance requirements of installations andequipment in electric power networks. lt is primarily meant for the operators of electric powernetworks, particularly those of public power supplies,including High-Voltage DC transmission(HvDC). This scope does not include:
railway networks,
installations of end consumer networks,installations for electric power generation.
Crises handling, e.g. in emergency situations, is not within the scope of this document.
NOTE Consumer networks (e.g. networks of chemical companies, traffic lights and street lighting) are installationswhich are not used to distribute electric energy to further consumers. The main scope covers public networks, butthe general recommendations can be applied to other networks.

combination of all technical and managerial actions intended to retain an object in, or restoreit to, a state in which it can perform as required
[SOURCE: IEC 60050-192:2015,192-06-01,modified – In the definition, “item” has been re-placed with “object”.][1] 1
maintenance conceptmaintenance policy
definition of the maintenance objectives, line of maintenance,indenture levels,maintenancelevels, maintenance support, and their interrelationships
Note 1 to entry: The maintenance concept provides the basis for maintenance planning,determining supportabil-ify requiremenls. and developing lagiistic support.
corrective maintenance
maintenance carried out after fault detection to effect restoration
[SOURCE: IEC 60050-192:2015,192-06-06, modified – Note 1 to entry has been deleted.] [1]
preventive maintenance
maintenance carried out to mitigate degradation and reduce the probability of failure
[SOURCE: IEC 60050-192;2015,192-06-05,modified -The second term and Note 1 to entryhave been deleted.] [1]
condition-based maintenance
preventive maintenance based on the assessment of physical condition
Note 1 to entry: Condition-based maintenance is derived from the analysis and determination of parameters whichcharacterize the deterioration of the object
[SOURCE: IEC 60050-192:2015,192-06-07,modified – Note 1 to entry has beenchanged.] [1]
periodic maintenancetime-based maintenance
maintenance carried out in accordance with a specified time schedule
Note 1 to entry: Periodic maintenance may identify the need for some corrective maintenance action.
[SoURCE: IEC 60050-192;2015,192-06-12,modified – The terms defined have beenchanged.] [1]
reliability-centred maintenanceRCM
systematic method for determining the respective maintenance actions and associated fre-quencies, based on the probability and consequences of failure
Note 1 to entry: RCM studies may be conducted at any indenture level of a system.
Note 2 to entry: Data used may be derived from analysis (e.g.FMECA) and experience (e.g.FRACAS).
Note 3 to entry: RCM studies may provide feedback to initiate modifications of design or procedures to effect im-provements.

maintenance taskmaintenance action
sequence of elementary maintenance activities
EXAMPLE Fault localization,fault diagnosis,repair,and function checkout.
Note 1 to entry: Maintenance can be completely divided into the following tasks:
