Vibration Analysis for GENSET Condition Monitoring
Measuring vibration levels at key points on a generator set (GENSET) is one of the most reliable methods for monitoring equipment health and performance. Establishing baseline vibration data at installation and performing routine vibration measurements over time allows operators to detect changes that may indicate developing issues. Through ongoing vibration monitoring and spectral analysis, our vibration analysts can accurately identify when maintenance is needed—helping prevent costly failures, reduce downtime, and extend the life of your GENSET.
Types of Vibration Monitoring Programs
There are three primary types of vibration monitoring strategies used to track equipment health and reliability. The right plan depends on factors such as available maintenance personnel, budget for vibration sensors, monitoring hardware, and supporting infrastructure. Each vibration monitoring program has unique advantages and limitations. The table below outlines the three vibration monitoring plans, along with the key benefits and challenges of each approach.

Route-Based Data Acquisition (DAQ)
With a route-based vibration monitoring system, technicians use a single vibration sensor and DAQ (data acquisition) device to collect readings along a specified route. Data is captured in separate files and stored on a set schedule—monthly, quarterly, or annually. This method is cost-effective but requires more technician involvement.
Multiple Sensor DAQ
In this approach, technicians temporarily install 10–20 vibration sensors to capture synchronized data in a single file. Measurements are taken periodically (monthly, quarterly, or yearly) and provide detailed insight into equipment condition. Because the data is synchronized, it enables advanced troubleshooting and predictive maintenance.
Permanent Vibration Monitoring System
A permanent monitoring system involves installing 10–20 vibration sensors full-time, allowing continuous data collection. Measurements are logged automatically into a database on a set schedule or on demand. Alarms can be configured to trigger when vibration levels exceed thresholds. With fully synchronized data, this system delivers the most advanced diagnostics, real-time monitoring, and long-term equipment protection.
Genset Vibration Testing Standards
Reliable generator performance depends on proper genset vibration testing and analysis. Monitoring vibration levels ensures durability, efficiency, and long-term reliability, while also helping prevent costly breakdowns. A variety of international standards provide guidelines for measuring, evaluating, and managing vibration in generator sets. Below are the key standards commonly applied in genset vibration analysis:
ISO 8528-9
This part of the ISO 8528 series focuses specifically on vibration measurement and evaluation for reciprocating engine-driven generator sets. It defines measurement methods, evaluation criteria, and expected vibration levels to ensure genset performance and reliability.
ISO 10816 / ISO 20816
These standards provide criteria for evaluating machine vibration on both rotating shafts and non-rotating parts. ISO 20816 is especially relevant to large industrial machines and low-speed generators, making it applicable to many genset installations.
API 546 / ISO 10440-1
Developed for large rotating machinery, these standards address vibration analysis and balancing of key components such as shafts and bearings. They are highly applicable to generator sets where rotating elements play a critical role.
ANSI / EASA AR100
While not genset-specific, this standard covers recommended practices for repairing rotating electrical equipment. It includes vibration testing as part of post-repair quality control, making it valuable for maintaining genset reliability after service.
MIL-STD-810
This military standard outlines environmental and vibration testing for equipment used in demanding conditions. For gensets deployed in military or rugged environments, it ensures performance under extreme operating conditions.
IEC 60034-14
IEC 60034-14 applies to electrical machines with shaft heights of 56 mm and above. It establishes methods for measuring and evaluating vibration severity, helping protect against long-term wear and operational issues.
