The lesson will discuss the significance of condition monitoring especially for EHV and UHV power transformers. It will deal with critical parameters that require monitoring and their significance. The limits for critical parameter set by IEC standard IEC60422-2013 will be discussed along with consequences if the limits are allowed to cross. Author will talk about the recommended actions when critical oil parameters cross the set limits.
IEC 60422 standard will be compared with IEEE 57.106-2015 standard and the key differences between the two will be discussed.
Keywords: condition monitoring, IEC60422, IEEE 57.106,2015, critical parameters, corrective actions, water, acidity, oxidation
The content of this lesson is fully vendor agnostic but it is sponsored by Ergon.
