Advanced testing key to assessing rotating machine failure risks

The reliability of rotating electrical machines hinges on advanced diagnostic techniques to predict and prevent failures effectively.

Assess the risk of failure in rotating machines Rotating electrical machines, such as motors and generators, are essential for power generation and industrial applications. Dependable reliability and availability are, therefore, crucial during their operational life.

On-going condition assessments

Premature failure may lead to significant economic losses due to unexpected outages and possible equipment damage. Over time, thermal, electrical, and mechanical stress factors influence motor and generator failure. For an accurate failure risk assessment, accurate, up-to-date condition information about machines and their components is essential to plan their maintenance or replacement effectively. During routine maintenance outages, the more extended downtime of the machine is used to perform various inspections, off-line tests, and measurements. An important aspect of these inspections is electrical testing, which assesses the quality of the insulation and reveals contact problems and other potential sources of error.

Various electrical tests evaluate the condition.
