It is not possible to forecast when an individual transformer will fail, but we can forecast how the failure probability develops over time. What does the “safe” remaining life depend on?
The purpose of a measurement is to identify signs of degradation or impending failure, using appropriate indicators. When applying measuring techniques for condition assessment, one of the main issues is the choice of an adequate set of techniques from the abundance of available options.
Presently, continuous monitoring is predominantly applied to selected high voltage transformers, in particular, transformers that are hard to access, have a strategic function, or lack redundancy
Dr. Jos Wetzer, our regular columnist in his article ‘Transformer measurement policies for optimum asset management value’ in our October edition shares useful guidelines.
What are the benefits of using condition assessment and what the effectiveness of mitigating risks are? What does measuring policy depend on? What are expected costs?
How to achieve an effective and efficient condition assessment for maintenance applications and population screening? What is a funnel or sieve approach? What statistical screening techniques are and how to employ them?
