Full title and description

St ISO 13373-7-2017 — Condition monitoring and diagnostics of machines — Vibration condition monitoring — Part 7: Diagnostic techniques for machine sets in hydraulic power generating and pump-storage plants. This part gives practical, vibration‑based guidelines and step‑by‑step procedures for vibration diagnostics of hydropower units, with examples of machine and component fault symptoms.

Abstract

ISO 13373-7:2017 provides guidance on specific procedures to consider when carrying out vibration diagnostics of various types of machine sets in hydraulic power generating and pump‑storage plants (hydropower units). It is intended for condition monitoring practitioners, engineers and technicians and includes practical diagnostic approaches and examples of fault symptoms for a range of components and machine types.

Scope

This standard covers vibration diagnostic techniques specific to machine sets used in hydraulic power generating and pump‑storage plants. It addresses recommended measurement and diagnostic procedures, symptom tables and examples to assist practitioners in identifying likely fault causes (mechanical, hydrodynamic, structural and support‑related) for hydropower units. It is focused on practical field diagnostics rather than exhaustive theory.

Key topics and requirements

• Guidance on vibration measurement and diagnostic workflow for hydropower machine sets (detection → analysis → probable cause).
• Typical symptom tables and example fault signatures for bearings, shafts/rotors, impellers, draft tubes, guide vanes and foundations.
• Recommended signal types and processing approaches for diagnosis (time‑waveform review, spectrum analysis, envelope techniques, order/shaft‑speed related checks).
• Practical measurement location guidance and inspection sequencing for effective troubleshooting.
• Interpretation principles and reporting considerations to support maintenance decisions and follow‑up actions.

Typical use and users

Primary users are condition monitoring practitioners, vibration analysts, reliability engineers, maintenance technicians and consultants working at hydropower stations or on pump‑storage plants. The document is used to design inspection procedures, interpret vibration data for hydropower machines and support remedial maintenance planning.

Q: What does it cover?

A: It covers recommended vibration diagnostic procedures, symptom tables and examples for common faults in hydropower machine sets, and provides guidance on measurement practice and interpretation to support field diagnostics.

Q: Who typically uses it?

A: Condition monitoring practitioners, vibration analysts, reliability and maintenance engineers, plant technicians and consultants involved with hydropower and pump‑storage equipment.

Q: Is it current or superseded?

A: The standard was published in August 2017 and is the current published edition; ISO records indicate a draft revision (ISO/DIS 13373‑7) has been prepared, so users should check for a newer edition or draft status with their national body or ISO for the latest revision progress.
