ISO 19283-2020 pdf free.Condition monitoring and diagnosticsof machines — Hydroelectric generating units.
This document focuses on recommended condition monitoring techniques for detecting and diagnosingdeveloping machine faults associated with the most common potential failure modes for hydro unitcomponents. It is intended to improve the reliability of implementing an effective condition monitoringapproach for hydroelectric generating units (hydro units). It is also intended to help create a mutualunderstanding of the criteria for successful hydro unit condition monitoring and to foster cooperationbetween the various hydropower stakeholders.
This document is intended for end-users， contractors,consultants，service providers，machinemanufacturers and instrument suppliers.
This document is machine-specific and is focused on the generator, shaft/bearing assembly, runner (andimpeller for pumped storage applications), penstock(including the main inlet valve), spiral case and theupper draft tube of hydro units.It is primarily intended for medium to large sized hydro units with morethan 50 MVA installed capacity, but it is equally valid for smaller units in many cases. lt is applicableto various types of turbines such as Francis,Kaplan, Pelton,Bulb and other types.Generic auxiliarysystems such as for lubrication and cooling are outside the scope, with the exception of some monitoringtechniques that are related to condition monitoring of major systems covered by this document, such asoil analysis.Transmission systems, civil works and the foundation are outside the scope.
This document covers online (permanently installed) and portable instrument condition monitoringand diagnostic techniques for operational hydro units. Offline machine testing, i.e. that which is onlydone during shutdown, although very important, is not part of the scope of this document. Nor is one-time acceptance and performance testing within the scope. The condition monitoring techniquespresented in this document cover a wide range of continuous and interval-based monitoring techniquesunder generalized conditions for a wide range of applications. Therefore, the actual monitoringapproach required for a specific application can be different than that which is recommended in thisgeneralized document.ISO 19283 pdf download.
